ABSTRACT:
The invention relates to a signalling system for vehicles wherein an independent light signal is provided at both the front and rear of a vehicle for a situation wherein the vehicle is both moving and the brakes are being applied or released by the operator of the vehicle. The signal is provided by lights located at the rear and the front of the vehicle which are purple in color, for example. Actuation of the lights is dependent upon two electrical signals, one based on motion of the vehicle and the other based upon actuation of the braking system of the vehicle. The intelligence offered by the signal to an observer is that observation of the purple light indicates that the vehicle is both in motion and that a braking operation is in progress.
