Do these bolt straight onto factory brackets?

Yes, these use factory mounting points — no drilling or custom brackets required. Existing fastener holes line up with the OEM setup.

Do I need to order bulbs separately?

Bulbs are not included. Check your owner's manual or existing headlight assembly for the correct bulb type before ordering.

Will these need any prep before installation?

Inspect the mounting surface for corrosion or debris before fitting. Clean contact points on the vehicle to ensure a tight seal and proper alignment.
