1. Open the bonnet and observe the layout of the car parts on the back of the headlight. If there is not enough space, go to a professional "4S" shop to replace them. Determine the headlamp model of your car, and pay attention to the identification model of the lower part of the outer glass of the headlamp.
 2. Screw off the lamp cover, and note that the method of removing the lamp cover varies slightly depending on the vehicle model.
 3. Pull out the lamp holder with power cord with force. When pulling out, pay attention to pressing the lamp by hand to avoid damage.
 4. Release the lamp holder circlip to take out the lamp, and then reinstall the new bulb. The process of reassembly is the reverse of disassembly, which will not be repeated here. Note that the dust cover must be screwed when reinstalling to prevent the headlight from being invaded by rain and dust.
