Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     This invention relates to an automobile compound water-proof tail light, particularly to one provided with LED lamps for various light sources combined in a single case and positioned at the tail of an automobile or a tug boat, and kept in a stable water proof condition, and each light source clearly separated from one another for easy discernment.  
         [0003]     2. Description of the Prior Art  
         [0004]     Conventional automobile compound waterproof tail lights are generally provided with incandescent lights as light sources for indicating a tail light, a brake light, a direction changing light, a side indicating light, a car width indicating light and a license plate light. The compound waterproof taillight is provided with waterproof covers, rubber gaskets for preventing water from flowing or seeping in its interior. But they are liable to get damaged in its seal by high temperature, or rainfall. When they are used in a tugboat, they may often emerge in seawater, with high temperature suddenly dipped in very cold seawater to worsen its seal to let water flowing or seeping in.  
         [0005]     A Sealed Tail Light for a Boat Trailer exposed in a U.S. Pat. No. 5,060,121 enclosed in this description makes use of traditional incandescent lights as light sources, and having a base  11  and a capsule  8  are boned together by glue or welded by a supersonic wave machine for sealing a light bulb  9  and a light bulb  10  in its interior for preventing water or moist from flowing or seeping in. However, traditional incandescent lights consumes much electricity, do not endure long, and generates high temperature but weak light beam, hardly meeting safety demand of recent traffic conditions. Moreover, the main light, the side indicating light and a license plate light are not clearly separated so it is quite confusing to discern what it really indicates.  
       SUMAMRY OF THE INVENTION  
       [0006]     The purpose of the invention is to offer an automobile compound waterproof taillight possible to separately indicating various functions of lights and making use of LED lights consuming low power, sealed with waterproof glue, and having a long service life.  
         [0007]     One of the feature of the invention is a bottom base of an opaque case-like shape, having a front side closed with a main light cap colored and transparent, a left side closed with a side light cap colored and transparent, an upper side closed with a car width indicating light cap, and a bottom side provided with a center opening closed with a license plate indicating light cap.  
         [0008]     A second feature of the invention is a main light base opaque, fixed in the bottom base, having a case body, and a fix base extending from the case body for a side light base to fix on. Further, a first electric circuit board, a main light set facing the main light cap, a license plate light set facing the license plate light cap and closed with a lamp cover are all fixed in the case body. A separating plate is provided to separate the license plate light set from the main light set, and waterproof glue is poured in the case body to seal the first electric circuit board, the main light set and the license plate light set and the lamp cover together as integral.  
         [0009]     A third feature of the invention is an opaque side light base fixed on the fix base, which has a second electric circuit board, a car width indicating light set facing the license plate light cap and a side indicating light set. A separating plate is provided to separate the car width indicating light set from the side indicating light set and the main light set. Further, waterproof glue is poured in the side light base to seal the second electric circuit board, the car width indicating light set and the side indicating light set together as integral.
