To use this fog light film, first clean the surface of your Morimoto XB LED fog lights thoroughly. Then carefully peel the backing off the film and apply it smoothly onto the fog lights, making sure to remove any air bubbles. When it comes to maintenance, simply wash it with mild soap and water. Avoid using abrasive cleaners as they can scratch the film. Also, don't try to remove the film forcefully as it may damage your fog lights.
