[0002] Headlights are essential safety components for electric vehicles. They can provide lighting and warning when the surrounding environment is dark. Among them, light leakage is a major problem that needs to be solved when designing headlights. When observing the lit headlights from a certain angle, you will find that light will leak out from the gaps in certain parts, which has a certain impact on the overall aesthetics and practicality of the headlights. In particular, the existing dimmable headlights on the market, due to their own structural limitations and cost considerations, when adjusting the light angle, the problem of light leakage at the edge gaps of the headlights can often only be ignored. As electric vehicle users have increasingly higher requirements for the use experience of headlights, some other headlights solve the light leakage problem by adding light-blocking parts, but this greatly increases the complexity of the headlight structure and the production cost.

[0022] like Figure 3 As shown, the dimming module includes a dimming bracket 6, a dimming buckle 7, and a dimming screw 8. Rotating shafts 9 are arranged on both sides of the dimming bracket 6. The rotating shafts 9 are rotatably connected to the rotating slots 10 in the bottom shell 1. One end of the dimming screw 8 threadedly connected to the bottom of the dimming bracket 6 is connected to the bottom of the dimming bracket 6 through the dimming buckle 7, and the other end extends out of the bottom shell 1. The back side of the light-emitting module 4 is fixedly connected to the dimming bracket 6. By moving the dimming screw 8 forward and backward, the dimming bracket 6 rotates around the rotating shaft 9, thereby changing the light emission angle of the light-emitting module 4.
