The invention relates to a multi-color gear indicator lamp structure. The multi-color gear indicator lamp structure comprises a cover plate, a PCB and a plurality of LED lamps arranged on the PCB, andis characterized in that a plurality of light guide plates are arranged on the PCB, and the plurality of light guide plates are in one-to-one correspondence with gears; grooves are formed in the sidefaces of the light guide plates, the plurality of LED lamps are located at the positions of the grooves correspondingly, and the thickness of the light guide plates is 0.1 mm larger than the height of the LED lamps; reflecting paper is attached to the upper surface and the lower surface of each light guide plate, the upper surface of the cover plate is provided with and displays gear characters,the lower surface of the cover plate is provided with a plurality of light isolation plates, and the plurality of light isolation plates are used for separating the gear characters from one another, so that light is prevented from being mixed; and a plurality of clamping legs are arranged on the edge of the cover plate, the cover plate covers the PCB, and the plurality of clamping legs are fastened to the edge of the PCB. According to the structure, the gear characters can be uniformly illuminated, the structure is compact and small in occupied space, and the gear indicator lamps of 1-8 colorscan be arranged according to the requirement of the displayed gears.
