If you originally had factory cab lights, you do not need to drill holes in the roof of your truck. Our cab lights are designed to be direct replacements for your OEM lights.
If you didn't originally have cab lights, we offer a retrofit kit that will come with roof templates to easily allow you to drill the necessary holes. Using our kit, you will not have to dremel squares on the roof (typically how the competition requires you to do), you will simply drill circular holes instead which is a much easier procedure.
Our installation video will walk you through the full procedure. If you have any questions our support team is always happy to help if you have any questions!
