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: A dashboard height-adjusting apparatus, used for the adjustment of the assembly of upper and lower units of the dashboard, the upper unit having a plurality of fastening hooks and the lower unit having a plurality of assembling sockets for engagement, the assembling socket received in the dashboard height-adjusting apparatus. The dashboard height-adjusting apparatus comprises a hook. unit formed at the bottom part of the height-adjusting apparatus, the hook unit folded horizontally to hook onto the lower edge of the wall side of the assembling socket; an extended section extending vertically from the hook unit; a covering section extending horizontally from the top of the extended section, the covering section being parallel to the hook unit and covering the upper edge of the wall side of the assembling socket; and a hook section being a flexible element and extending vertically and downwardly from the covering section in order to engage with the lower edge of the fastening hook of upper unit.

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.
