Abstract
A light emitting diode perimeter lamp assembly generally includes a housing a receiving pocket formed therein for receiving a circuit board with a plurality of light emitting diodes mounted thereon. In addition, a culminating lens having a plurality of light directing elements is positioned within the receiving pocket of the housing above the circuit board such that light emitted from said plurality of light emitting diodes passes through said plurality of light directing elements. An outer lens is also mounted over the receiving pocket. When the perimeter lamp is installed on a truck body, the bottom side of the lamp housing is at an acute angle to a ground surface while the back end of the perimeter lamp is adjacent and parallel to a truck wall such that light emitted by the plurality of light emitting diodes is projected onto the ground surface adjacent to the truck wall.
