Will this bolt straight to my truck without any modifications?

Yes. This mounts at factory rocker points — no drilling, cutting, or bracket fabrication needed. Line it up and bolt it down.

Does the bulb come installed, or do I need to buy that separately?

Assembly only — bring your own bulb. Check your OEM part number or service manual for the correct bulb type before ordering.

What condition is this in — does it need any paint or prep work?

Chrome housing ships ready to install. No sanding, priming, or painting required. Inspect for any shipping damage before mounting.
