EXHIBIT 4.7

THE WARRANTS REPRESENTED BY THIS CERTIFICATE ("WARRANTS") AND THE UNDERLYING
WARRANT SHARES ("WARRANT SHARES") HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"). THE WARRANTS MAY NOT BE OFFERED
OR SOLD UNLESS THE WARRANTS AND WARRANT SHARES HAVE BEEN REGISTERED UNDER THE
SECURITIES ACT OR AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE, AS EVIDENCED
BY AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY.

THE WARRANTS REPRESENTED BY THIS CERTIFICATE MAY NOT BE TRANSFERRED, SOLD,
PLEDGED, HYPOTHECATED AND ENCUMBERED EXCEPT PURSUANT TO THE PROVISIONS CONTAINED
HEREIN.

                        WARRANTS TO PURCHASE COMMON STOCK

         EMRISE CORPORATION, a Delaware corporation (the "Company"), hereby
grants to HAYDEN COMMUNICATIONS, INC. (the "Holder") one hundred thousand
(100,000) warrants (the "Warrants") for the purchase of common stock of the
Company (the "Common Stock"), with each whole Warrant entitling the Holder to
purchase one share of Common Stock (each a "Warrant Share" and collectively the
"Warrant Shares") on the terms and subject to the vesting and other conditions
set forth in this warrant certificate (the "Warrant Certificate").

         1. TERM AND VESTING. Subject to Holder continuing to provide services
to the Company pursuant to a letter agreement dated November 3, 2004 between the
Company and Holder ("Letter Agreement"), the Warrants shall vest in three
installments as follows: (i) on November 3, 2004, the Warrants shall vest as to
25,000 Warrant Shares ("First Installment"); (ii) on March 3, 2005, the Warrants
shall vest as to an additional 25,000 Warrant Shares ("Second Installment"); and
(iii) on June 3, 2005, the Warrants shall vest as to the remaining 50,000
Warrant Shares ("Third Installment"), at which time the Warrants shall be vested
as to all 100,000 Warrant Shares. The Warrants may be exercised, in whole or in
part, at any time and from time to time on or after their respective vesting
date and until 5:00 P.M. Pacific Time on third anniversary of their respective
vesting date (each an "Exercise Period"); provided that an Exercise Period will
be extended to the extent that the Holder attempts during the Exercise Period to
exercise Warrants for which there are not then available shares of Common Stock,
until such time as such shares become available. As an example of an Exercise
Period, Warrants that vest as part of the Second Installment shall be
exercisable from March 3, 2005 through March 3, 2008.

         2. EXERCISE PRICE. The initial exercise price of each whole Warrant
shall be as follows: (i) $0.85 per Warrant Share for Warrants that vest in the
First Installment; (ii) $1.00 per Warrant Share for Warrants that vest in the
Second Installment; and (iii) $1.15 per Warrant Share for Warrants that vest in
the Third Installment (each an "Exercise Price"). The Exercise Price shall be
subject to adjustment as provided in Section 6.

<PAGE>

         3. EXERCISE OF WARRANTS.

                  3.1 GENERAL EXERCISE PROCEDURES. The Warrants are exercisable
on the terms provided herein at any time during their respective Exercise
Periods by the surrender of this certificate to the Company at its principal
office together with the Notice of Exercise annexed hereto duly completed and
executed on behalf of the Holder, accompanied by payment in full, in immediately
available funds, of the amount of the aggregate Exercise Price of the Warrant
Shares being purchased upon such exercise. The Holder shall be deemed the record
owner of such Warrant Shares as of and from the close of business on the date on
which this certificate is surrendered together with the completed Notice of
Exercise and payment in full as required above or, if the Exercise Period is
extended for an attempted exercise as provided in Section 1 above, at such later
date as there are a sufficient number of shares of Common Stock available for
issuance pursuant to the attempted exercise (the "Exercise Date"). The Company
agrees that the Warrant Shares so purchased shall be issued as soon as
practicable thereafter. It shall be a condition to the exercise of the Warrants
that the Holder or any transferee hereof provide an opinion of counsel
reasonably satisfactory to the Company that the Warrants and the Warrant Shares
to be delivered upon exercise thereof have been registered under the Securities
Act or that an exemption from the registration requirements of the Securities
Act is available.

                  3.2 CASHLESS EXERCISE. Notwithstanding the provisions in
Section 3.1 regarding payment of the Exercise Price in immediately available
funds, the Holder may elect to receive a reduced number of Warrant Shares in
lieu of tendering the Exercise Price in immediately available funds. In such
case, the number of Warrant Shares to be issued to the Holder shall be computed
using the following formula:

                                    X = Y X (A-B)
                                        ---------
                                            A

         where:   X = the number of Warrant Shares to be issued to the Holder;
                  Y = the number of Warrant Shares to be exercised under this
                      Warrant Certificate;
                  A = the Market Price Per Share (as defined in Section 3.3);
                      and
                  B = the Exercise Price.

                  3.3 FRACTIONAL INTEREST; MARKET PRICE. The Company shall not
issue any fractional shares of scrip representing fractional shares upon the
exercise of this Warrant. With respect to any fraction of a share resulting from
the exercise hereof, the Company shall pay to the Holder an amount in cash equal
to such fraction multiplied by the current fair market value per share of Common
Stock (the "Market Price Per Share"), determined as follows:

                           (a) If the Common Stock is listed on a national
securities exchange or admitted to unlisted trading privileges on such an
exchange or is listed on Nasdaq, the current fair market value shall be the last
reported sale price of the Common Stock on such exchange or Nasdaq on the last
business day prior to the date of exercise of this Warrant, or if no such sale
is made on such day, the mean of the closing bid and asked prices for such day
on such exchange or Nasdaq;

                                      -2-

<PAGE>

                           (b) If the Common Stock is not so listed or admitted
to unlisted trading privileges or quoted on Nasdaq, the current fair market
value shall be the mean of the last bid and asked prices reported on the last
business day prior to the date of the exercise of this Warrant (i) by the OTC
Bulletin Board, or (ii) if reports are unavailable under clause (i) above, by
the National Quotation Bureau Incorporated or its successor; or

                           (c) If the Common Stock is not so listed or admitted
to unlisted trading privileges and bid and asked prices are not so reported, the
current fair market value shall be an amount, not less than book value,
determined in such reasonable manner as may be prescribed by the Company's Board
of Directors in good faith.

         4. WARRANTS CONFER NO RIGHTS OF STOCKHOLDER. The Holder shall not have
any rights as a stockholder of the Company with regard to the Warrant Shares
prior to the Exercise Date for any actual purchase of Warrant Shares.

         5. INVESTMENT REPRESENTATION. Neither the Warrants nor the Warrant
Shares issuable upon the exercise of the Warrants have been registered under the
Securities Act or any state securities laws. The Holder acknowledges by signing
this certificate that, as of the date of this Warrant and at the time of
exercise that: (a) the Holder has acquired the Warrant or the Warrant Shares, as
the case may be, for the Holder's own account; (b) the Holder has acquired the
Warrants or the Warrant Shares, as the case may be, for investment and not with
a view to distribution; and (c) either the Holder has a pre-existing personal or
business relationship with the Company or its executive officers, or by reason
of the Holder's business or financial experience the Holder has the capacity to
protect the Holder's own interests in connection with the transaction. The
Holder agrees, by acceptance of this certificate, that any Warrant Shares
purchased upon exercise of the Warrants may have to be held indefinitely, until
registered and qualified for resale pursuant to the Securities Act, or until an
exemption from registration is available, as evidenced by an opinion of counsel
reasonably satisfactory to the Company. The Holder, by acceptance of this
certificate, consents to the placement of a restrictive legend (the "Legend") on
the certificates representing any Warrant Shares that are purchased upon
exercise of the Warrants during the applicable restricted period under Rule 144
or any other applicable restricted period under the Securities Act. The Legend
shall be in substantially the following form:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED. ("SECURITIES ACT"). SUCH
         SHARES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD,
         TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE
         REGISTRATION STATEMENT FOR SUCH SHARES UNDER THE SECURITIES ACT, UNLESS
         IN THE WRITTEN LEGAL OPINION (APPROVED BY THE COMPANY) OF COUNSEL
         SATISFACTORY TO THE COMPANY, THE SECURITIES MAY BE TRANSFERRED WITHOUT
         REGISTRATION PURSUANT TO RULE 144 PROMULGATED UNDER THE SECURITIES ACT
         OR ANY OTHER AVAILABLE EXEMPTION.

                                      -3-

<PAGE>

         6. ADJUSTMENT FOR CHANGES IN CAPITAL STOCK. If the Company at any time
during the Exercise Period shall, by subdivision, combination or
reclassification of securities, change any of the securities into which the
Warrants are exercisable into the same or a different number of securities of
any class or classes, the Warrants shall thereafter entitle the Holder to
acquire such number and kind of securities as would have been issuable as a
result of such change with respect to the Warrant Shares if the Warrant Shares
had been outstanding immediately prior to such subdivision, combination, or
reclassification. If shares of the Company's Common Stock are subdivided into a
greater number of shares of Common Stock, the Exercise Price for the Warrant
Shares upon exercise of the Warrants shall be proportionately reduced and the
number of Warrant Shares shall be proportionately increased; and conversely, if
shares of the Company's Common Stock are combined into a smaller number of
shares of Common Stock, the Exercise Price shall be proportionately increased,
and the number of Warrant Shares shall be proportionately decreased.

         7. LOSS, THEFT, DESTRUCTION OR MUTILATION OF CERTIFICATE. Upon receipt
by the Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of any certificate representing the Warrants or the
Warrant Shares (referred to herein as the "original certificate"), and in case
of loss, theft or destruction, of indemnity or security reasonably satisfactory
to the Company, and upon reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the original
certificate if mutilated, the Company will make and deliver a new certificate of
like tenor in lieu of the original certificate.

         8. GENERAL. This Warrant Certificate shall be governed by and construed
in accordance with the laws of the State of California, without regard to choice
of law principles. Any disputes arising in connection with this Warrant
Certificate shall be resolved in the federal or state courts located in Orange
County, California. The headings herein are for purposes of convenience and
reference only and shall not be used to construe or interpret the terms of this
Warrant Certificate. The terms of this certificate may be amended, waived,
discharged or terminated only by a written instrument signed by both the Company
and the Holder. All notices and other communications from the Company to the
Holder shall be mailed by first-class registered or certified mail, postage
pre-paid, to the address furnished to the Company in writing by the last Holder
who shall have furnished an address to the Company in writing.

         9. PIGGYBACK REGISTRATION. If at any time prior to October 29, 2005
there is not a registration statement covering all of the Warrant Shares and the
Company shall determine to prepare and file with the Securities and Exchange
Commission a registration statement relating to an offering for its own account
or the account of others under the Securities Act of any of its equity
securities, other than on Form S-4 or Form S-8 (each as promulgated under the
Securities Act) or their then equivalents relating to equity securities to be
issued in connection with any acquisition of any entity or business or equity
securities issuable in connection with stock option or other employee benefit
plans, then the Company shall send to Holder written notice of such
determination and, if within five business days after receipt of such notice,
Holder shall so request in writing, the Company shall include in such
registration statement all or any part of the Warrant Shares that such holder
requests to be registered, subject to customary underwriter cutbacks. Holder

                                      -4-

<PAGE>

agrees that if Warrant Shares are included in a registration statement, Holder
will promptly complete and provide the Company with selling security holder
questionnaires in such form as may be requested by the Company.

         IN WITNESS WHEREOF, the Company and Holder have executed this Warrant
Certificate on or about February ___, 2005, to memorialize the grant of Warrants
that occurred on November 3, 2004 pursuant to the Letter Agreement.

EXHIBIT 4.8

THE WARRANTS REPRESENTED BY THIS CERTIFICATE ("WARRANTS") AND THE UNDERLYING
WARRANT SHARES ("WARRANT SHARES") HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"). THE WARRANTS MAY NOT BE OFFERED
OR SOLD UNLESS THE WARRANTS AND WARRANT SHARES HAVE BEEN REGISTERED UNDER THE
SECURITIES ACT OR AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE, AS EVIDENCED
BY AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY.

THE WARRANTS REPRESENTED BY THIS CERTIFICATE MAY NOT BE TRANSFERRED, SOLD,
PLEDGED, HYPOTHECATED AND ENCUMBERED EXCEPT PURSUANT TO THE PROVISIONS CONTAINED
HEREIN.

                        WARRANTS TO PURCHASE COMMON STOCK

         EMRISE CORPORATION, a Delaware corporation (the "Company"), hereby
grants to HAYDEN COMMUNICATIONS, INC. (the "Holder") twenty-five thousand
(25,000) warrants (the "Warrants") for the purchase of common stock of the
Company (the "Common Stock"), with each whole Warrant entitling the Holder to
purchase one share of Common Stock (each a "Warrant Share" and collectively the
"Warrant Shares") on the terms and subject to the vesting and other conditions
set forth in this warrant certificate (the "Warrant Certificate").

         1. TERM AND VESTING. The Warrants shall vest in full on the date
hereof. The Warrants may be exercised, in whole or in part, at any time and from
time to time on or after their vesting date and until 5:00 P.M. Pacific Time on
January 24, 2008 ("Exercise Period"); provided that the Exercise Period will be
extended to the extent that the Holder attempts during the Exercise Period to
exercise Warrants for which there are not then available shares of Common Stock,
until such time as such shares become available.

         2. EXERCISE PRICE. The initial exercise price of each whole Warrant
shall be $2.00 per Warrant Share ("Exercise Price"). The Exercise Price shall be
subject to adjustment as provided in Section 6.

         3. EXERCISE OF WARRANTS.

                  3.1 GENERAL EXERCISE PROCEDURES. The Warrants are exercisable
on the terms provided herein at any time during their respective Exercise
Periods by the surrender of this certificate to the Company at its principal
office together with the Notice of Exercise annexed hereto duly completed and
executed on behalf of the Holder, accompanied by payment in full, in immediately
available funds, of the amount of the aggregate Exercise Price of the Warrant
Shares being purchased upon such exercise. The Holder shall be deemed the record
owner of such Warrant Shares as of and from the close of business on the date on
which this certificate is surrendered together with the completed Notice of
Exercise and payment in full as required above or, if the Exercise Period is
extended for an attempted exercise as provided in Section 1 above, at such later
date as there are a sufficient number of shares of Common Stock available for
issuance pursuant to the attempted exercise (the "Exercise Date"). The Company

<PAGE>

agrees that the Warrant Shares so purchased shall be issued as soon as
practicable thereafter. It shall be a condition to the exercise of the Warrants
that the Holder or any transferee hereof provide an opinion of counsel
reasonably satisfactory to the Company that the Warrants and the Warrant Shares
to be delivered upon exercise thereof have been registered under the Securities
Act or that an exemption from the registration requirements of the Securities
Act is available.

                  3.2 CASHLESS EXERCISE. Notwithstanding the provisions in
Section 3.1 regarding payment of the Exercise Price in immediately available
funds, the Holder may elect to receive a reduced number of Warrant Shares in
lieu of tendering the Exercise Price in immediately available funds. In such
case, the number of Warrant Shares to be issued to the Holder shall be computed
using the following formula:

                                    X = Y X (A-B)
                                        ---------
                                            A

         where:   X = the number of Warrant Shares to be issued to the Holder;
                  Y = the number of Warrant Shares to be exercised under this
                      Warrant Certificate;
                  A = the Market Price Per Share (as defined in Section 3.3);
                      and
                  B = the Exercise Price.

                  3.3 FRACTIONAL INTEREST; MARKET PRICE. The Company shall not
issue any fractional shares of scrip representing fractional shares upon the
exercise of this Warrant. With respect to any fraction of a share resulting from
the exercise hereof, the Company shall pay to the Holder an amount in cash equal
to such fraction multiplied by the current fair market value per share of Common
Stock (the "Market Price Per Share"), determined as follows:

                           (a) If the Common Stock is listed on a national
securities exchange or admitted to unlisted trading privileges on such an
exchange or is listed on Nasdaq, the current fair market value shall be the last
reported sale price of the Common Stock on such exchange or Nasdaq on the last
business day prior to the date of exercise of this Warrant, or if no such sale
is made on such day, the mean of the closing bid and asked prices for such day
on such exchange or Nasdaq;

                           (b) If the Common Stock is not so listed or admitted
to unlisted trading privileges or quoted on Nasdaq, the current fair market
value shall be the mean of the last bid and asked prices reported on the last
business day prior to the date of the exercise of this Warrant (i) by the OTC
Bulletin Board, or (ii) if reports are unavailable under clause (i) above, by
the National Quotation Bureau Incorporated or its successor; or

                           (c) If the Common Stock is not so listed or admitted
to unlisted trading privileges and bid and asked prices are not so reported, the
current fair market value shall be an amount, not less than book value,
determined in such reasonable manner as may be prescribed by the Company's Board
of Directors in good faith.

         4. WARRANTS CONFER NO RIGHTS OF STOCKHOLDER. The Holder shall not have
any rights as a stockholder of the Company with regard to the Warrant Shares
prior to the Exercise Date for any actual purchase of Warrant Shares.

                                      -2-

<PAGE>

         5. INVESTMENT REPRESENTATION. Neither the Warrants nor the Warrant
Shares issuable upon the exercise of the Warrants have been registered under the
Securities Act or any state securities laws. The Holder acknowledges by signing
this certificate that, as of the date of this Warrant and at the time of
exercise that: (a) the Holder has acquired the Warrant or the Warrant Shares, as
the case may be, for the Holder's own account; (b) the Holder has acquired the
Warrants or the Warrant Shares, as the case may be, for investment and not with
a view to distribution; and (c) either the Holder has a pre-existing personal or
business relationship with the Company or its executive officers, or by reason
of the Holder's business or financial experience the Holder has the capacity to
protect the Holder's own interests in connection with the transaction. The
Holder agrees, by acceptance of this certificate, that any Warrant Shares
purchased upon exercise of the Warrants may have to be held indefinitely, until
registered and qualified for resale pursuant to the Securities Act, or until an
exemption from registration is available, as evidenced by an opinion of counsel
reasonably satisfactory to the Company. The Holder, by acceptance of this
certificate, consents to the placement of a restrictive legend (the "Legend") on
the certificates representing any Warrant Shares that are purchased upon
exercise of the Warrants during the applicable restricted period under Rule 144
or any other applicable restricted period under the Securities Act. The Legend
shall be in substantially the following form:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED. ("SECURITIES ACT"). SUCH
         SHARES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD,
         TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE
         REGISTRATION STATEMENT FOR SUCH SHARES UNDER THE SECURITIES ACT, UNLESS
         IN THE WRITTEN LEGAL OPINION (APPROVED BY THE COMPANY) OF COUNSEL
         SATISFACTORY TO THE COMPANY, THE SECURITIES MAY BE TRANSFERRED WITHOUT
         REGISTRATION PURSUANT TO RULE 144 PROMULGATED UNDER THE SECURITIES ACT
         OR ANY OTHER AVAILABLE EXEMPTION.

         6. ADJUSTMENT FOR CHANGES IN CAPITAL STOCK. If the Company at any time
during the Exercise Period shall, by subdivision, combination or
reclassification of securities, change any of the securities into which the
Warrants are exercisable into the same or a different number of securities of
any class or classes, the Warrants shall thereafter entitle the Holder to
acquire such number and kind of securities as would have been issuable as a
result of such change with respect to the Warrant Shares if the Warrant Shares
had been outstanding immediately prior to such subdivision, combination, or
reclassification. If shares of the Company's Common Stock are subdivided into a
greater number of shares of Common Stock, the Exercise Price for the Warrant
Shares upon exercise of the Warrants shall be proportionately reduced and the
number of Warrant Shares shall be proportionately increased; and conversely, if
shares of the Company's Common Stock are combined into a smaller number of
shares of Common Stock, the Exercise Price shall be proportionately increased,
and the number of Warrant Shares shall be proportionately decreased.

         7. LOSS, THEFT, DESTRUCTION OR MUTILATION OF CERTIFICATE. Upon receipt
by the Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of any certificate representing the Warrants or the

                                      -3-

<PAGE>

Warrant Shares (referred to herein as the "original certificate"), and in case
of loss, theft or destruction, of indemnity or security reasonably satisfactory
to the Company, and upon reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the original
certificate if mutilated, the Company will make and deliver a new certificate of
like tenor in lieu of the original certificate.

         8. GENERAL. This Warrant Certificate shall be governed by and construed
in accordance with the laws of the State of California, without regard to choice
of law principles. Any disputes arising in connection with this Warrant
Certificate shall be resolved in the federal or state courts located in Orange
County, California. The headings herein are for purposes of convenience and
reference only and shall not be used to construe or interpret the terms of this
Warrant Certificate. The terms of this certificate may be amended, waived,
discharged or terminated only by a written instrument signed by both the Company
