Will this bolt straight onto my truck without modification?

Yes. This assembly mounts at factory rocker points — no drilling, cutting, or frame work required. Line it up and fasten at the original attachment locations.

Do I need to adjust the headlight beam after installation?

Aim check is always a good idea after any headlight swap. Most vehicles have vertical and horizontal adjustment screws inside the engine bay or behind the assembly. Refer to your service manual for the exact location and procedure on your truck.

Is the bulb included with this assembly?

The assembly ships as-is. Bulb type and installation details vary by year and trim level — confirm your bulb type in the owner's manual before ordering separately if needed.
