A vehicle system is disclosed that includes a vehicle lamp assembly including a plurality of LEDs that emit white light so as to function as an illuminator light. The lamp assembly also may include a plurality of LEDs that emit colored light to function as a signal light. The lamp assembly may include a camera. The lamp assembly may serve as a CHMSL or as a tail light. The system also includes a controller that rapidly pulses the LEDs at a rate that is imperceivable by the human eye.
