Abstract
A device for indicating the aim, at least in bearing, of the optical axis of the reflector of a motor vehicle headlight relative to a longitudinal axis of the vehicle, wherein the device comprises apparatus for establishing a reference direction and suitable for being mounted on a fixed portion of the vehicle to define a reference direction that is well determined relative to the longitudinal axis apparatus. Apparatus is also included for establishing the direction of the optical axis of the reflector and is fixed relative to the reflector and distinct from a surface of the reflector for generating its beam. Finally, an indicator is provided for establishing the position of the optical axis direction relative to the reference direction. Indications thus given by the device enable the reflector to be adjusted after is has been mounted on the vehicle.
