Abstract: A lighting apparatus for providing a substantially uniformly illuminated light emitting surface, the apparatus comprising first and second light sources generating flux patterns including light rays that diverge about first and second central light rays, respectively and a light guide member having substantially straight first and second en sections and a curved section, the first end section having a proximal end and a distal end and formed about a first light axis, the second end section having a proximal end and a distal end and formed about a second light axis, the curved section including first and second ends that are linked to the distal ends of the first and second end sections, respectively, the guide forming a front surface and an oppositely facing textured back surface along each of the end sections and the curved section, the curved section forming a bend such that the back surface is concave and the front surface is convex along the curved section length, at least a portion of the back surface ta

Abstract: A lighting system for a towed off-highway vehicle has a left and right hazard warning lamps that flash in unison when the vehicle is not turning. When the vehicle is turning, the hazard warning lamp on the side of the turn flashes, while the other hazard warning lamp is illuminated steadily. Left and right turn indicator lamps are operated by a control circuit that receives signals which operate the hazard warning lamps. The control circuit responds to those signals by rendering the turn indicator lamps inactive when the vehicle is not turning, and operates the left and right turn indicator lamps in the same manner as the left and right hazard warning lamps, respectively, when the vehicle is turning.

Abstract: An improved warning light includes a flashing strobe light bulb and a plastic lens which has incorporated in the plastic material an effective amount of a fluorescent material such as a dye or pigment, which converts the radiation emitted by the strobe light to the preferred wave length of the fluorescent material. In a preferred embodiment, especially suited for use as a warning light on vehicles, the strobe light is surrounded by a cylindrical lens of polycarbonate or acrylic plastic which has the fluorescent dye incorporated therein and the bulb and the lens are protected from the elements by a transparent dome.
