Using these cab roof lights is easy. First, make sure your Ford Super Duty truck from 2017 - 2024 didn't come with factory - installed cab roof lights. If it did, you'll need a different part number as mentioned. Then, use the provided screws and wiring harness to install the lights. You can use the Bluetooth app on your phone or tablet to control the lights and change colors. For installation, drill 2 small screw holes and a 1/4' round hole for the wires. You can also use the installation template (part # 264342T) we offer. As for maintenance, keep the lens clean. Since it's UV - treated, it can withstand sunlight well. If you notice any issues with the LED lights, check the wiring first. The LED running lights have a long 50,000 - hour lifespan, so you don't have to worry about replacing them often.
