Using your new cab roof light lens set is a breeze. First, make sure your Ford Super Duty truck from 2017 - 2024 has factory - installed cab roof lights. If it does, you can start the installation. The kit comes with screws and a wiring harness, so you just need to follow the included instructions to install the lights. To control the lights, download the Bluetooth app on your phone or tablet. Once connected, you can easily change the colors and settings of the RGB LEDs. As for maintenance, since the lens is UV - treated and made of military - grade reinforced ABS plastic, it's quite durable. But it's still a good idea to clean it regularly with a soft cloth and mild cleaner. Remember, this set is only for trucks that originally had factory - installed cab roof lights. If your truck didn't, you'll need a different part number as mentioned in the product description.
