  • Patent number: 5860735
    Abstract: A light glare reducing device being all or partially constructed of light transmitting materials with light reflecting surfaces in different designs. When the light glare reducing devices or lenses are placed over lighting sources they reduce the high glare and blinding effects of the light sources. Increasing the light output of lighting sources when used with lenses can maintain the lighting level while reducing glare. When used for automotive usage alternative automotive headlights are used. The combined usage of the alternative headlights and the lenses provides roadway and side of the roadway lighting without high glare to oncoming vehicles, bicyclists, pedestrians and animals. The existing automotive headlight system can be maintained so that the high beam headlights can be used if necessary or desirable.

  • Patent number: 5860726
    Abstract: A resilient mount for rotating warning light systems includes a mounting base having a plurality of mounting feet, each of which includes a special grommet mounted within an aperture formed therein. The grommets are selectively shaped so as to absorb and dissipate substantially all shock loads which would ordinarily be delivered to the rotating warning light system, and particularly, to the fragile bulb itself. The resiliently mount further prevents noise from being transmitted from the rotating light back into the vehicle to which the mounting base is connected.

  • Patent number: 5845990
    Abstract: A device for an automotive vehicle to signal braking, deceleration, turning of the vehicle or an emergency situation. The device has two bodies facing rearwardly, mounted near the top of the back or the highest point of the vehicle adjacent the sides of the vehicle. Each body has a base and a cover with translucent lenses. Light sources and reflectors are disposed on the base for illuminating the lenses to create the signaling as required. Lighting one or more lenses in the cover indicate braking while lighting an arrow shaped lens in the cover and a side lens facing out from the vehicle indicate intended turning. The light transmitted through the lenses in the cover is directed downwardly either by a downward tilt to the cover or by directional configurations formed on the lenses. The lenses signifying braking are formed from red material while the arrow shaped and side lenses signifying turning are formed from red or yellow material.

  • Patent number: 5842777
    Abstract: The present invention describes a flashlight powered with an oblong power supply. The flashlight is designed to be compact and watertight. It is protected against the entrance of moisture with a single O-ring seal. The case of the flashlight can be injection molded and can be used without secondary fabrication such as gluing. The flashlight includes a light module which is held to prevent its rotation relative to the case to thereby maintain a desired polarity with the power supply permitting a variety of polarity responsive lamps or circuits to be incorporated into the design. Some configurations create light output color or intensity changes by reversing the batteries. On-Off switching is accomplished using a mechanism independent of the location of the power supply so that power supply movement will not cause inadvertent energizing of the lamp or hazardous sparks.
