Do these mount to existing factory holes or do I need to drill?

These use factory mounting points—no drilling required. Test-fit the assembly against your fender before final fastening to confirm alignment.

Does the kit come with bulbs installed?

The assembly ships complete, but confirm bulb type and condition before installation. You may need to source replacement bulbs depending on your application.

Are these plug-and-play or do they need wiring work?

Mounting hardware and structural assembly are included. Electrical connections depend on your existing fender light wiring—verify compatibility with your truck's system before committing to installation.
