ABSTRACT:
A warning light system is provided for use in a motor vehicle having a cab region for accommodating a vehicle driver, and a brake light system including a voltage source and an electrically actuated lamp disposed at the rear of the vehicle. The warning light system provides a warning system to motorists rearward of the vehicle. The motorists have on average a reaction time above a reaction time threshold. The warning light system in the present invention exposes motorists rearward of the vehicle to at least one flash of the electrically actuated lamp of the vehicle brake light system. Each of the flashes have a duration less than the average reaction time threshold of motorists. In an alternative embodiment, the warning light system of the present invention may be coupled to an electrically actuated lamp which is mounted rearward on the vehicle, and is independent of the vehicle brake light system.
