Dear Mr. Marinoff:

This responds to your letter asking about Federal Motor Vehicle Safety Standard No. 105, Hydraulic Brake Systems. You stated that you believe the standard requires vehicles to have a warning light system that indicates loss of pressure or low fluid level in the braking system and asked if this belief is correct.

Your understanding about Standard No. 105 is correct. I have enclosed a copy of that standard for your information. The requirements for brake system indicator lamps are set forth at section S5.3 of the standard.

Sincerely,

Paul Jackson Rice Chief Counsel

Enclosure /ref:105 d:l0/23/9l
