Do I need to buy a bulb separately?

Bulb inclusion is not confirmed—plan to source the correct replacement bulb for your truck before installation.

Will this bolt straight to my truck without any modification?

Yes. This assembly mounts at the factory headlight points with no drilling, cutting, or frame modification needed.

What if the headlight doesn't seal properly after install?

Test-fit the assembly before considering any permanent sealing method. If gaps appear, confirm the mounting bracket is fully seated at all factory points.
