Abstract

Abstract A spot light assembly includes a support tube journalled upon a frame, having a handle assembly secured over one end of the tube and a head assembly secured over the other end of the tube and mounting a spot light. Rotation of the handle assembly in a vertical plane effects the corresponding angular adjustment of the spot light. A rotatable drive shaft within the tube at its ends extends respectively into the handle assembly and head assembly. An upright stud is supported in the head assembly. The handle assembly includes a handle rotatable in a horizontal plane. Intermeshing gears on the handle, on end portions of the drive shaft and on the stud are connected to the spot light whereby rotation of the handle in a horizontal plane effects a corresponding rotation of the spot light. The improvement lies in the drive shaft at one end being in brush contact with the stud. A lead wire interconnects the stud and spot light, and a normally open switch in the head assembly is connected to an electrical power source and includes a spring-biased retracted contact spaced from the other end of the drive shaft. The drive shaft within the support tube and the gears thereon, and the drive gear in the handle assembly and the driven gear in the head assembly are all insulated. The drive shaft is removable from the spot light assembly so that it is possible to cut the drive shaft and the support tube to any desired length at point of installation on a vehicle.
