Will this bolt straight onto my car without any modification?

Yes. This assembly mounts at factory rocker and chassis points—no drilling, cutting, or adapter hardware needed. Hand-tighten the existing fasteners and you're done.

Does the bulb come installed, or do I need to source one separately?

The assembly ships empty. You'll need a standard halogen replacement bulb—ask your parts supplier for the correct wattage for your model year.

Can I return this if it doesn't fit or I change my mind?

Contact ModSupply customer service with your order number and the reason. Return and refund policies are handled on a case-by-case basis.
