This invention relates to a vehicle brake lighting system having a novel brake delay lighting system utilized with a conventional vehicle brake lighting system. The conventional vehicle brake lighting system includes a battery member being a power source connected through a brake pedal switch to brake light members. Depression of a brake pedal closes the brake pedal switch to energize the brake light members in a conventional manner. The brake delay lighting system includes a delay timer member which is interconnected by a timer circuit means to the conventional vehicle brake lighting system. The delay timer member is operable on release of contact with the brake pedal and opening of the brake pedal switch to provide for the continued illumination of the brake light members for a set time period such as plus or minus eight seconds. The brake delay lighting system is provided with a fail-safe system so that the conventional vehicle brake lighting system continues to operate in a normal conventional manner even on mechanical or electrical failure of the brake delay lighting system. The brake delay lighting system automatically resets to zero if the brake pedal is depressed during a timing cycle and again times out after release of the brake pedal for the full time cycle.
