			     TRANS-LUX CORPORATION
		  CERTIFICATION OF THE CHIEF FINANCIAL OFFICER
	       PURSUANT TO RULE 13a-14(a) UNDER THE EXCHANGE ACT

I, Angela D. Toppi, certify that:

1.  I have reviewed this quarterly report on Form 10-Q of Trans-Lux Corporation;

2.  Based on my knowledge, this report does not contain any untrue statement of
    a material fact or omit to state a material fact necessary to make the
    statements made, in light of the circumstances under which such statements
    were made, not misleading with respect to the period covered by this report;

3.  Not applicable;

4.  The registrant's other certifying officer and I are responsible for
    establishing and maintaining disclosure controls and procedures (as defined
    in Exchange Act Rules 13a-15 (e) and 15d-15(e)) and internal control over
    financial reporting (as defined in Exchange Act Rules 13a-15 (f) and
    15d-15(f)) for the registrant and have:

	a) designed such disclosure controls and procedures, or caused such
	   disclosure controls and procedures to be designed under our
	   supervision, to ensure that material information relating to the
	   registrant, including its consolidated subsidiaries, is made known to
	   us by others within those entities, particularly during the period in
	   which this report is being prepared;

	b) designed such internal control over financial reporting, or caused
	   such internal control over financial reporting to be designed under
	   our supervision, to provide reasonable assurance regarding the
	   reliability of financial reporting and the preparation of financial
	   statements for external purposes in accordance with generally
	   accepted accounting principles;

	c) evaluated the effectiveness of the registrant's disclosure controls
	   and procedures and presented in this report our conclusions about the
	   effectiveness of the disclosure controls and procedures, as of the
	   end of the period covered by this report based on such evaluation;
	   and

	d) disclosed in this report any change in the registrant's internal
	   control over financial reporting that occurred during the
	   registrant's most recent fiscal quarter (the registrant's fourth
	   fiscal quarter in the case of an annual report) that has materially
	   affected, or is reasonably likely to materially affect, the
	   registrant's internal control over financial reporting; and

5.  The registrant's other certifying officer and I have disclosed, based on our
    most recent evaluation of internal control over financial reporting, to the
    registrant's auditors and the audit committee of the registrant's board of
    directors (or persons performing the equivalent functions):

	a) all significant deficiencies and material weaknesses in the design or
	   operation of internal control over financial reporting which are
	   reasonably likely to adversely affect the registrant's ability to
	   record, process, summarize and report financial information; and

	b) any fraud, whether or not material, that involves management or other
	   employees who have a significant role in the registrant's internal
	   control over financial reporting.
