Do I need a bulb, or does it come installed?

Assembly ships without a bulb installed. You'll need to source a compatible halogen replacement separately and install it into the housing before mounting.

Will this mount without any drilling or bracket work?

Yes. Factory mounting points line up directly — install with existing hardware and fasteners from your vehicle's OEM setup.

Can I return this if the fitment isn't right?

Test-fit the assembly before final installation. If you encounter fitment issues, contact support with photos of the mounting area for guidance on your specific situation.
