Abstract
Abstract An auxiliary brake lamp for motor vehicles comprises a holder which includes a track (7) which has a double-T-shape in cross section and which is adherable to a rear window. A lamp housing (2) is engagingly shoved onto the holder. A holding spring (5) arranged in the lamp housing clamps a first flange of the double-T-track between it and the housing. An electrical coupling of the lamp to a vehicle power supply is provided by a flat plug engagement device (12). That is, the double-T-track is electrically coupled with a current source of the motor vehicle and the holding spring is electrically coupled with a light bulb (17) of the lamp. A contact plate formed as a flat lug (11) as part of the first flange of the double-T-track produces a conductive coupling between the lamp and the holder by sliding contact on the holding spring.
