Abstract: In order to reduce the height of an auxiliary stop or turn indication lamp which may be mounted either immediately adjacent the rear windshield or housed on top of the trunk lid of an automotive vehicle, a light bulb is arranged in an essentially vertically extending base section of a housing so that the filament thereof is located at a level just above that of the floor of an elongate capsule-like upper section provided on top of the base member. The filament is arranged parallel with a lens or similar light transmissive member which is disposed in an opening formed in the upper section.
