Do I need to remove the factory corner lights first?

Yes. The old lights will need to come out before these go in. Work from inside the fender if accessible, or remove trim panels as needed to reach the mounting area.

Are bulbs included with these corner lights?

The product data confirms the assemblies only. Source the correct bulb type for your vehicle's corner light socket and have them ready before installation.

Will these fit without modification?

These are designed for direct factory fitment. Test-fit before securing — if gaps appear, verify mounting tabs and trim panel alignment first.
