Abstract
An anti-collision safety light control for a vehicle includes a microprocessor which receives one or more inputs and controls an output of at least one indicator or signaling device in response to the inputs. The microprocessor is continuously powered or energized when the vehicle is in use, such that the indicator may be modulated in situations when the brake pedal of the vehicle is not applied. Preferably, an accelerometer may be included with the safety light system to provide a deceleration signal to the microprocessor, which may determine whether the deceleration is at or above one or more threshold levels and correspondingly modulate the indicator in accordance with the particular threshold level encountered. The microprocessor may modulate the indicator independent of actuation of the brake pedal by a driver of the vehicle.
