An adjustable rear lamp is disclosed to allow the adjustment of a lamp housing
within the lamp cavity of an automobile's body frame. A threaded bolt is inserted
into an opening in the sheet metal of an automobile. A nut is attached to the threaded
bolt. The threaded bolt surrounds a threaded shaft, and one end of the threaded
shaft is attached to the lamp housing. The nut and threaded bolt may be rotated,
engaging the threaded shaft and moving the threaded shaft into or out of the lamp
cavity. The movement of the threaded shaft and the lamp housing allows the lamp
housing to be positioned precisely within the lamp cavity.
