Will these bolt straight into my factory mounting points?

Yes. These are designed to use the OEM bracket locations — no drilling or chassis modification needed. Your existing hardware works.

Do I need to replace the bulbs, or do they come installed?

Bulbs are not included. Your current bulbs transfer over to these housings, so swap them from your old headlights before install.

Can I return these if they don't fit or look right once I open them?

ModSupply handles returns on a case-by-case basis — reach out to support with photos if there's a fitment issue and they'll work with you.
