ABSTRACT:
An integrated combination of a headlamp section and a sidelamp section for a vehicle, with the sidelamp section being oriented and rotatable at a predetermined wrap-around side facing angle with respect to the forward lighting direction of the headlamp section. This angle may be typically on the order of 90.degree. so that the sidelamp provides good continuous wrap-around side lighting and good night vision for persons riding in the vehicle or exiting therefrom. The sidelamp section may be operated in response to the turning on and off of the dimmer bulb within the headlamp section or it may be operated independently of the operation of the dimmer bulb by the use of an OR gate logic circuit in combination with an electro-mechanical relay and switch. This circuit is operable for energizing and de-energizing the relay and switch in response to power applied to any one of a plurality of parallel connected inputs of the OR gate logic circuit. In addition, one of these inputs is connected to operate a sidelamp rotational motion control stage for controlling the rotational motion of the sidelamp in both horizontal and vertical planes to thereby provide automatic and instantaneous side lighting for the automobile.
