An overhead light swivel bracket assembly mounts a light fixture spaced apart a fixed distance and position from a surface to be illuminated such as a billboard. A long bracket has a distal end for the light fixture, and a vertical capped sleeve at the proximal end for rotation on a fixed vertical cylinder, enabling the light fixture to rotate pivotally about the vertical cylinder in a horizontal arc between an extended position in which the light fixture is at the fixed distance and position to illuminate the surface from above and a retracted position in which the light fixture is adjacent a worker positioned behind the surface for servicing by the worker.
