Using this cab roof light set is easy. First, make sure your Ford Super Duty truck from 2017 - 2024 doesn't have factory - installed cab roof lights. If it does, get the right part as mentioned. Then, use the provided installation template (part # 264342T) to mark the 2 small screw holes and a 1/4' round hole for wires on your truck. Install the lights with the included screws and wiring harness. You can control the lights using your phone or tablet via the Bluetooth app. When it comes to maintenance, since the lens is UV - treated and the LEDs have a long lifespan, you don't need to worry much. Just clean the lens regularly with a soft cloth to keep it looking good. Also, check the wiring connections occasionally to make sure everything is working properly.
