Using this fog light kit is easy. First, make sure your car is turned off. Then, install the fog lights in the designated spots on your Subaru WRX. Attach the fog light bezels for a sleek look. Connect the fog lights switch and use the included hardware to secure everything in place. When using the fog lights, remember to turn them on only when visibility is poor, like in fog, heavy rain, or at night. This helps you see better and also makes your car more visible to others. For maintenance, regularly check the bulbs to see if they need replacing. Keep the fog lights and bezels clean by gently wiping them with a soft cloth. If you notice any issues with the switch or the lights not working properly, it's best to get it checked by a professional.
