Using these fog light bezels is a breeze. First, make sure your car is turned off. Locate the area where the old bezels are installed and carefully remove them. Then, take out the new Noble bezels and connect them using the plug-and-play feature. Once connected, turn on your accessory power, and you'll see the bright white DRLs light up. When you use your turn signal, they'll switch to amber. Remember, the turn signal function won't work with adaptive headlights. As for maintenance, you can clean the gloss black housing with a mild car cleaner and a soft cloth. Avoid using abrasive materials that could scratch the finish. And since the fog lights aren't included, you'll need to take care of them separately according to their own maintenance requirements. If you encounter any installation issues, you might want to seek help from a professional mechanic.
