Install the lamp carefully and find a good route for the wiring harness to prevent water from getting into the vehicle. Then, plug in the harness and test all the functions. Remember, you can enable or disable the F1 blinking feature according to your preference by following the included instructions. As for maintenance, keep the lamp clean with a soft cloth.

That way, your rear fog light will serve you well for a long time.
