A transparent single piece lens assembly covers the LEDs, the lens assembly has a corresponding plurality of convex lenses, each convex lens forward of each LED, the lens assembly attached to the rear portion of the channel. Forward edges of the side flanges of the channel extend farther forward from the rear surface than the lens assembly for protection.
