Abstract: A retractable truck light assembly for trucks that provides increased lighting and visibility when a truck is towing a trailer. The truck light assembly includes a retractable light housing that is affixed to the truck bed side wall. The housing further includes a pivotal mount whereby the truck light housing swivels outward from the truck body to an extended position and swivels inward to the truck body to a retracted position. The truck light assembly also includes an adjustable rod attachable to the truck bed side wall. The adjustable rod includes a concave receptor shaped and positioned to receive the truck light housing in its retracted position such that the truck light housing does not substantially protrude beyond the aerodynamic plane of the truck bed side wall. In the preferred embodiment, the truck light system includes a pair of truck light assemblies for positioning on the driver and passenger sides of the truck, respectively.

Abstract: A light emitting diode (LED) assembly is provided for use as an airplane position light which meets Federal Aviation Regulation lighting requirements and lasts longer than conventional incandescent and halogen position lights, while being relatively lightweight, cheap, and requiring relatively little power for operation. The LED assembly includes a first plurality of circuit boards in electrical communication with a base circuit board, wherein each circuit board of the first plurality of circuit boards is parallel to every other one of the first plurality of circuit boards, but is disposed at an acute angle to the base circuit board. The LED assembly also includes a second plurality of circuit boards in electrical communication with the base circuit board, wherein each circuit board of the second plurality of circuit boards is disposed at a different angle to the base circuit board such that the second plurality of circuit boards form a fan-shaped structure.

Abstract: A air filter and light apparatus for filtering the air of a room while simultaneously illuminating the room. The air filter and light apparatus includes a base portion having a bottom wall. The bottom wall has a peripheral edge. A side wall extends away from and is integrally coupled to the peripheral edge. The side wall has a plurality of slots therein. A motor is fixedly mounted to the bottom wall. A plurality of wires deliver power to the motor. The wires are operationally coupled to a power source and to the motor. A fan for directing airflow from a central portion of the base through the slots is rotatably coupled to the motor. A cover for the base portion has a central portion having a bore therein. A light source illuminates the cover. The light source is mounted in the cover. A filter for filtering the air is mounted in the bore of the cover. An actuator controls the motor and the light source.

Abstract: A handcuff key that is partially enclosed in a grip housing having the ends of the handcuff key plate extending out of the grip housing. The external portions of the middle of the handcuff key plate are ribbed and attach to the external end portions of the handcuff key plate. The grip housing has a depression button on one side and a threaded notched cover that can be removed for cell replacement on the other. The grip housing includes a cell that sits in a recess on one side of the handcuff key plate and is lined with a circular conductive strip. The recess surrounds a hole that is integrated in with the structure of the key. An insulated wire is connected to the circular conductive strip and runs to the terminals of two light emitting diodes and then to another conductive strip that is affixed to the internal side of a depression button. The two light emitting diodes sit in grooved slots of the grip housing and face opposite each other toward the respective ends of the handcuff key plate.

Abstract: A self-emission road device includes light emitting elements and a power unit, and has the light emitting elements emit light through a light emitting face of a protective board set at an upper part of the self-emission road device. For each light emitting face, four emission units are provided. Out of the four emission units, two emission units are designed for a straight road and light beams from these emission units are emitted in a direction whose horizontal component is perpendicular to the light emitting face. Two other emission units are designed for a curve and light beams from these emission units are emitted in a direction whose horizontal component forms a predetermined angle with the direction whose horizontal component is perpendicular to the light emitting face. The emission units for the straight road and curve are set in alternate order.
