Using these Lamin-x fog light covers is a breeze. First, clean the fog light surface thoroughly to ensure good adhesion. Then, peel the backing off the film and carefully stick it onto the fog light. The included tools can help you smooth out any air bubbles. When it comes to color film, choose the one that matches your style preference. As for maintenance, simply wash the covers with mild soap and water regularly. Avoid using abrasive cleaners as they may scratch the film. Remember, these covers are designed to protect your fog lights, so don't apply them in extremely cold or hot weather as it might affect the adhesion. If you ever have any issues, the 5 - year warranty has you covered.
