Abstract: An illuminated bicycle having a body frame, a handlebar and wheels formed of hollow tubular members made of plastic material that allows light to be transmitted radially through their side walls. A high intensity lamp is mounted at a predetermined location within one of the hollow tubular members. A bundle of flexible elongated optical fibers have their one end positioned adjacent the high intensity lamp so that light therefrom would be transmitted through the optical fibers. The optical fibers are threaded throughout the hollow tubular members of the bicycle body frame so that when the lamp is illuminated the hollow tubular members will glow and make them highly visible at night. The lamp may be powered by batteries or a small bicycle generator.

Abstract: A plastic lamp housing is molded in one piece with two cantilevers extending forwardly from its rear wall for supporting a metal made reflector and a light bulb out of direct contact with all the inside surfaces of the lamp housing. The reflector thermally covers at least the top and bottom and rear sides of the light source for the reduction of heat transmission to the lamp housing. Depending from the lamp housing, a lamp standard has a hollow extending therethrough in communication with the interior of the lamp housing through a heat release opening formed in the bottom of the lamp housing. The lamp standard is for use in mounting the lamp on a hollow structural part of a motor vehicle in the vicinity of its rear window. Therefore, by creasing an opening in the hollow vehicle part, the heated air within the lamp housing can be vented into the hollow lamp standard and thence into the hollow vehicle part, instead of into the interior of the vehicle body.
