·First of all, we can judge whether the daytime running lights need to be after-sales according to the number of daytime running lights that are not on.
·If only one of the daytime running lights does not work and it is newly installed on the car, we can check whether the plug of the lights is not correctly plugged in during installation. If so, then we can plug it back in.
·If only one of the daytime running lights does not work and it is installed for some time, then we can first check the other functions of the car, such as checking the car’s high beam and low beam lights, the car’s secondary line, the fuse and so on. If other functions on the vehicle are operating normally, we can contact the customer service of the purchase channel.
·If two daytime running lights on the car are both not on, you can directly contact the customer service of the purchase channel. Inform the time, photo, or video of the lamp installation. The customer service will analyze and carry out after-sales according to the condition of the daytime running lights.
