Abstract

A floodlight that is adapted to projecting a pattern of light from the housing of a vehicle exterior mirror on an area adjacent a portion of the vehicle in order to create a lighted security zone in that area. The pattern extends laterally onto the vehicle and downwardly and rearwardly of the mirror housing. In this manner, the lighted security zone extends from the vehicle door to the rear of the vehicle. An actuator for the floodlight includes a base unit in the vehicle and a remote transmitter wherein the base unit is responsive to a signal from the remote transmitter in order to actuate the floodlight. The actuator may further include a lockout device in order to prevent actuation of the floodlight during operation of the vehicle. A signal light is additionally included in the exterior mirror housing in order to project a second pattern of light from the mirror housing extending laterally away from the vehicle and rearwardly of the vehicle. In this manner, the second pattern cannot be directly observed by the driver of the vehicle but may be observed by the driver of another vehicle passing the equipped vehicle. The signal light operates in unison with a turn signal, brake signal, or both, of the equipped vehicle.
