The method to detect whether the headlight bulb is burnt out is as follows:
1. Check whether the fuse of the car headlight is normal. If the fuse is blown, it needs to be replaced in time.
2. Check whether the line is damaged. If the line is poorly spliced or loose, pull out the line plug, and then plug it in tightly.
3. Check whether the headlight relay and combination switch are faulty, and if so, replace them.
After the above three faults are eliminated, there is a high probability that the headlight bulb has burned out. If the voltage regulator of the car is faulty, it will cause the voltage to be too high and burn out the light bulb; A short circuit between them can also cause the bulbs in the car's headlights to burn out. In this case, SHINESELL AUTO recommends going to a professional auto repair shop for repairs.
