Abstract: A third brake light is attached to a rear deck door panel of a truck so as not to interfere with opening/closing of the door panel. The third brake light includes a base attached to the door panel of the truck and forming an exposed surface to which a plurality of illuminators, such as light-emitting diodes, light bulbs and cold light panels, is mounted. An electrical cable electrically connects the illuminators to an electricity system of the truck. A light-transmitting cover having a size and shape corresponding to the base is attached to the exposed surface of the base for shielding and protection of the illuminators.

Abstract: An automobile air filter comprising a filter element, an outer hood receiving the filter element, and a plurality of metal electrodes arranged in the filter element. Each pair of the metal electrodes is connected by a cable and pass through the outer hood. A high voltage generator circuit is installed at appropriate location of an automobile for generating instantaneous high voltage to provide instantaneous high voltage power to each pair of metal electrodes, so that the metal electrodes generate high voltage flashes and ozone to purify the air flowing in the filter element and increase oxygen content in the air intake in the engine.

Abstract: An instrument panel includes a base on which indicators are movably mounted and a transparent cover positioned above the base. An illuminating device includes a board interposed between the base and the cover. The board defines a number of recesses in a bottom surface thereof for respectively and movably accommodating the indicators therein. The board defines a number of cavities in an end thereof for receiving illuminators, such as light emitting diodes, of different colors therein. The illuminators are connected to and controlled by a control circuit whereby the illuminators are selectively actuated to light the instrument panel with light of different colors by conducting light through the board. Scales of first unit system are formed by means of etching or other suitable manners on the board. Scales of second unit system are formed on the base. The base is provided with an additional light source.

Abstract: A taillight module for motor vehicles attached and coupled to the license plate groove comprising a base, a casing, and a display plate. The base is coupled to the license plate groove. A plurality of lamps is disposed in the base. The lamps are coupled to the circuits of brake light, signal light, and headlight of the motor vehicle to provide an illumination source. The display plate is disposed between the housing and the base. The display plate has labels of text, graphics, and symbols on the surface of the display plate. The taillight module provides a third set of rear light structure for motor vehicles to clearly display a third brake light, signal lights, reverse light, or decorative lights through the lamps.
