Will this bolt directly to my vehicle without any modifications?

Yes. This assembly uses factory mounting points — no drilling, cutting, or fabrication needed. Line it up and secure it with your existing fasteners.

Do I need to buy the left side headlight separately?

This is the right-side unit only. If you need both headlights, order the left-side assembly as a separate purchase.

What type of bulb does this take, and is it included?

Bulb type is not specified in the product data — confirm compatibility with your vehicle's service manual or contact support with your VIN before ordering.
