Do these bolt straight into the factory cab light holes?

Yes. They mount at factory locations with no drilling or modifications needed. Verify your truck's specific mounting configuration before final assembly.

Will I need to run new wiring?

Factory wiring harnesses will need to be tested for compatibility with LED operation. Some trucks may require a load resistor or decoder module to prevent bulb-out warnings on the dash.

Can I install these myself?

Basic hand tools and access from under the headliner are all you need. Removal of trim panels varies by truck configuration—check your service manual for details on headliner access on your specific year.
