Abstract
The tail gate of a station wagon carries an electric lamp for automatically illuminating the adjacent portion of the body compartment when the tail gate is open. The lamp is energized from the battery of the vehicle through a pneumatic spring which biases the tail gate toward the open position. The two fastening eyes of the spring insulate the piston rod and cylinder of the spring from the tail gate and body of the vehicle respectively. A switch sealed in the spring conductively connects the piston rod and cylinder, otherwise insulated from each other, when the spring holds the tail gate open, terminals on the piston rod and cylinder outside the cylinder cavity being connected to the battery and the lamp respectively.
