Abstract
A lightweight utility vehicle brake lighting system comprising a brake pedal position sensor, a controller and a brake light circuit. The brake pedal position sensor senses the position, e.g., amount of depression, of a vehicle brake pedal. The controller of interprets a brake pedal position signal from the brake pedal position sensor to determine the position of the brake pedal. When the controller determines that the brake pedal has been depressed to initiate a braking operation of the vehicle, the controller transmits a brake light signal to an electronic switching device, such as a relay switch, of the brake light circuit. Upon receipt of the brake light signal, the electronic switching closes to complete, or close, the brake light circuit to enable a current flow through the brake light circuit, thereby illuminating at least one brake light of the vehicle.
