At the same time, a large amount of air can be introduced into the engine compartment, and the water tank for heat radiation can reduce the temperature of the automobile engine using air convection. However, due to the strong development of the automobile industry in recent years, the emphasis is on improving performance in the design of automobiles, and the overall shape of the exterior shape is also very important. The design tends to give the deepest impression on the overall appearance of the vehicle. Therefore, many automobile manufacturers decorate the original black grid water tank cover using electroplated decorative rods in order to improve the design of the entire vehicle.

  In addition, there are car owners who want to expand the modernity and techno feeling of automobiles and attach water tank covers with LED lights attached as running lights. However, since this LED light is exposed as it is on the surface of the water tank cover, the aesthetic effect is relatively inadequate, and the light source projects directly outside, producing a very strong light beam, It is easily dazzled by other drivers or pedestrians, which is counterproductive and indirectly affects driving safety.

  In view of the above, the hidden automobile light-emitting water tank cover designed by the present invention has the high-quality electroplating visual effect and the internal light source It is soft and transparent, has both visual and warning effects, and has no effect on driving safety.
