The more common one may be that the power in the battery has lost power, which leads to the lights. The lighting dims slowly and changes as the engine is running.

Secondly, it may also be that the resistance inside increases due to the heating of the wire, which reduces the illumination intensity of the light. Although it is not very bright, it still emits light. It is also possible that the relay of the light in the line or the contact point of the combination switch is damaged or bonded. The last situation is that there are many on-board electrical appliances used in the car, which makes the generator run under overload for a long period of time, which causes the diodes and coils inside to burn out, making the generator unable to generate electricity normally.
