US Patent 9132770 Vehicle illumination system

A vehicle includes a chassis, a bed assembly, and a light assembly. The chassis includes a frame member that defines a longitudinal direction. The bed assembly includes a deck coupled to the frame member and moveable between a transport position and a loading position. The light assembly includes a housing, a marker light coupled to the housing and positioned to deliver light across the longitudinal direction, and an indicator light coupled to the housing and positioned to deliver light in the longitudinal direction. The light assembly is coupled to the bed assembly to improve lateral and longitudinal visibility of the vehicle when the deck is in the transport position and the loading position.
