The invention relates to a light pipe which includes a more effective light collector which transmits a larger amount of illumination to a lens located adjacent the light pipe. A lamp assembly includes a housing having walls defining a chamber and an open front. A lamp is mounted in the housing as well as a lens which covers the open front of the housing. The lens has a portion which extends laterally of the housing chamber. A light pipe is mounted to the housing adjacent the lens for collecting and distributing the light from the lamp along the laterally-extending portion of the lens. For more effective transmission of the light in a light distribution portion of the light pipe, the light-distributing portion can be provided with grooves along a surface distal from the lens to direct light from the light-collecting portion toward the lens. A light-collecting portion of the light pipe can be provided with a parabolic collecting surface facing the lamp to increase the light collection capabilities of the light-collecting portion of the light pipe.
