activated when there are any variations in the fluid level in that part of the reservoir provided exclusively for the use of the system other than the brake system.
35.2.1.2.3.              As a check of function the 'Visible Indicator' shall be so designed that it operates when:
35.2.1.2.3.1.       the ignition or electrical control switch is turned from the "engine off" position to the "engine on" position, and the engine is not operating, and (unless a failure of the type described in clause 35.2.1.2.1 exists in the brake system, or in the event of an electrical failure of the 'Antilock System') it shall not operate when the engine is running;
35.2.1.2.3.2.       the ignition or electrical control switch is in the "engine start" position, and (unless a failure of the type described in clause 35.2.1.2.1 exists in the brake system, or in the event of an electrical failure of the 'Antilock System') it shall not operate after the return of the ignition or electrical control switch to the "engine on" position;
35.2.1.2.3.3.       the ignition or electrical control switch is in a position between the "engine on" position and the "engine start" position, which is designated by the 'Manufacturer' as a check position, and (unless a failure of the type described in clause 35.2.1.2.1 exists in the brake system, or in the event of an electrical failure of the 'Antilock System') it shall not operate after the return of the ignition or electrical control switch to the "engine on" position; or
35.2.1.2.3.4.       the engine start circuit is energised and (unless a failure of the type described in clause 35.2.1.2.1 exists in the brake system or in the event of an electrical failure of the 'Antilock System') it shall not operate when the "engine start" circuit is not energised.
35.2.1.2.3.5.       Where an 'Antilock System' is fitted the 'Visible Indicator', as a check of function, may continue to operate for up to 10 seconds following the activation as a check of function; or

         35.2.1.2.3.5.1 Notwithstanding the requirements of clause 35.2.1.2.3.1, the 'Visible Indicator' shall light up when the 'Antilock System' is energised and be extinguished at the latest when the vehicle reaches a speed of 10 km/h.

35.2.1.2.3.6.       For the purpose of this clause (35.2.1.2.3), for vehicles equipped with an automatic transmission, the operation as a check of indicator function is not required when the transmission control lever is in a "forward" or "reverse" drive position.
35.2.1.2.4.              The 'Visible Indicator' system shall be so designed that once having become operative to signal a brake failure it shall operate whenever the ignition or electrical control switch is in the "engine on" position and the fault remains uncorrected.
35.2.1.2.5.              The 'Visible Indicator' may take the form of an
