How to change the bulb of a car headlight, how to change the bulb of a car headlight

Installation: Carried out in the state of turning off the engine and cooling the car.

Before replacing the headlight bulb, in order to avoid being burned by the components in the engine compartment when changing the bulb, we need to confirm that the vehicle has been turned off and that it is in a cool state, and open the hood. Gloves should be worn when changing, which can not only protect your hands, but also facilitate handling.

Step 1: Unplug the bulb's power socket.

Step 2: After unplugging the power connector, remove the waterproof cover on the back of the bulb.

Step 3: Remove the bulb from the reflector. Bulbs are generally held in place by wire circlips, and some models also have a plastic base.

Step 4: Put the new bulb into the reflector, align it with the fixed position of the bulb, pinch the wire circlips on both sides and push it in, and fix the new bulb in the reflector.

Step 5: Re-close the waterproof cover, plug in the bulb power, and the replacement operation is complete.

Note: Avoid touching the bulb glass case directly with your hands.

Regarding the replacement of headlight bulbs, there are some precautions that car owners need to pay attention to. When choosing a new bulb, car owners should choose the right product according to the model of their original bulb.

When installing the bulb, do not touch the glass of the bulb directly with your fingers. This is because there is gas inside the bulb, and even the slightest oil stain on the finger sticking to the glass will shorten the life of the bulb, and there may be a danger of bursting after long-term use.

Effect: Contrast of illuminance before and after replacement.

For most car owners, a new bulb with slightly higher brightness and irradiation distance than the original car bulb is enough, and there is no need to pursue a more dazzling and expensive xenon bulb. Compared with the original car, the brightness of the new bulb we replaced this time has increased by 90% and the whiteness has increased by 10%. Judging from the actual illuminance comparison effect, the new bulb is indeed brighter and more practical.

When replacing the headlight bulb of the car, first of all, the vehicle needs to turn off the engine for more than 5 minutes, pull out the car key, wait for the engine to cool down completely, and then open the engine compartment cover after the headlight temperature has cooled down, so as not to burn the parts.

3. After installing the new bulb, put the dust cover back and close the engine compartment cover. Types of Car Lights:

1. Headlights: The headlights at the front end of the car are divided into low beams and high beams;
