Abstract
A vehicle includes a truck bed and a lighting assembly configured to illuminate the truck bed. The lighting assembly includes a light source, a collimator positioned in front of the light source, and an outer lens positioned in front of the collimator. The collimator and the outer lens establish a lens arrangement having a unitary body. The light generated by the light source is collected within the collimator and is directed at a downward angle toward a floor of the truck bed by the outer lens.
