1. A vehicular anti-collision safety light system for actuating an output of at least one indicator on a vehicle, said safety light system comprising:

  • a stop lamp configured to be mounted at a rear portion of the vehicle and operable in response to actuation of a brake pedal by a driver of the vehicle, said stop lamp comprising a plurality of light sources, said stop lamp being actuated to illuminate at a generally constant intensity while the brake pedal is actuated;

    an accelerometer which is operable to sense a deceleration of the vehicle; and

    , a microprocessor for receiving a deceleration input from said accelerometer and modulating the output of said plurality of light sources whereby said plurality of light sources is intermittently energized in response to said deceleration input, said microprocessor modulating the output of said plurality of light sources independent of actuation of the brake pedal of the vehicle, said microprocessor being operable to continue modulating the output of said plurality of light sources independent of actuation of the brake pedal for a period of time following said microprocessor receiving said deceleration input, an amount of said period of time being adjustable in response to a triggering level of said deceleration input received by said microprocessor, said triggering level corresponding to a deceleration level which is at a sufficient level to trigger said microprocessor to modulate the output of said plurality of light sources independent of actuation of the brake pedal.
