Using these fog lights is easy. First, find the factory mounting points on your vehicle and attach the fog lights using them. Then, connect the plug - and - play wiring to your factory fog light wiring. You can also choose to use the optional Lamin - X Yellow Film Kit for different lighting effects. When it comes to maintenance, keep the lens clean. You can use a soft cloth to wipe it gently. Since they are IP67 waterproof, they can withstand normal weather conditions, but avoid submerging them in water for a long time. If you notice any issues with the lights, check the wiring connections first. And remember, these fog lights come with a 10 - year warranty, so if there are any major problems, you can reach out for support.
