Based on this situation, not particularly skilled users should not risk their own replacement, so as not to damage the components inside the car, and the gains outweigh the gains. If there is enough space on the back of the lamp, you can change the following steps: change the front lamp 1. to open the hood of the engine and observe the layout of the car parts on the back of the headlight. If the space is not enough, then go to the professional "4S" store. Determine the type of headlights for the car.
