and/or which precludes the functioning of at least one of two independent service braking circuits;

         5.2.21.1.2. Where applicable, a yellow warning signal indicating an electrically detected defect within the vehicle braking equipment, which is not indicated by the red warning signal described in paragraph 5.2.21.1.1. above.

         5.2.21.2. The warning signals shall be visible, even by daylight; the satisfactory condition of the signals shall be easily verifiable by the driver from the driver's seat; the failure of a component of the warning devices shall not entail any loss of the braking system's performance.

         5.2.21.3. A specified failure or defect shall be signalled to the driver by the above-mentioned warning signal(s) not later than on actuation of the service braking control. The warning signal(s) shall remain displayed as long as the failure/defect persists and the ignition (start) switch is in the "on" (run) position

         5.2.21.4. The warning signal(s) mentioned above shall light up when the electrical equipment of the vehicle (and the braking system) is energised. With the vehicle stationary, the braking system shall verify that none of the specified failures or defects are present before extinguishing the signals. Specified failures or defects which should activate the warning signals mentioned above, but which are not detected under static conditions, shall be stored upon detection and be displayed at start-up and at all times when the ignition (start) switch is in the "on" (run) position, as long as the failure or defect persists.

6. TESTS

          Braking tests which the vehicles submitted for approval are required to undergo, and the braking performance required, are described in annex 3 to this Regulation.

         7. MODIFICATION OF VEHICLE TYPE OR BRAKING SYSTEM AND EXTENSION OF APPROVAL

         7.1. Every modification of the vehicle type or of its braking system shall be notified to the administrative department which approved the vehicle type. That department may then either:

         7.1.1. consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the vehicle still meets the requirements; or

         7.1.2. require a further report from the Technical Service responsible for carrying out the tests.

         7.2. Notice of confirmation, extension, or refusal of approval shall be communicated by the procedure specified in paragraph 4.3. above, to the Parties to the Agreement which apply this Regulation.

         7.3. The competent authority issuing the extension of approval shall assign a series of numbers to each communication form drawn up for such an extension.

8. CONFORMITY OF PRODUCTION

          The conformity of production procedures shall comply with those set out in the Agreement, Appendix 2 (E/ECE/324-E/ECE/TRANS/505/Rev.2) with the following requirements:

         8.1. A vehicle approved to this Regulation shall be so manufactured as to conform to the type approved by meeting the
