Abstract: A retractable truck light assembly for trucks that provides increased lighting and visibility when a truck is towing a trailer. The truck light assembly includes a retractable light housing that is affixed to the truck bed side wall. The housing further includes a pivotal mount whereby the truck light housing swivels outward from the truck body to an extended position and swivels inward to the truck body to a retracted position. The truck light assembly also includes an adjustable rod attachable to the truck bed side wall. The adjustable rod includes a concave receptor shaped and positioned to receive the truck light housing in its retracted position such that the truck light housing does not substantially protrude beyond the aerodynamic plane of the truck bed side wall. In the preferred embodiment, the truck light system includes a pair of truck light assemblies for positioning on the driver and passenger sides of the truck, respectively.
