Using these cab lights is straightforward. First, make sure your truck is turned off. Then, remove the existing OEM cab or clearance lights if you have them. Simply install the new cab lights from the Recon 264343BK Kit in their place. When it comes to maintenance, clean the smoked lenses regularly with a soft, damp cloth to keep them looking clear and stylish. Avoid using abrasive materials that could scratch the lenses. If you notice any issues with the high - power amber LEDs, check the connections to ensure they are secure. Keep in mind that these lights are designed specifically for 2017 - 2022 Ford F - Series trucks with 6.7L Powerstroke engines, so make sure your vehicle matches this specification before installation.
