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

Bulbs are not included — you'll use the existing bulbs from your vehicle or source compatible replacements separately. Install is straightforward: remove the old housings and plug the new ones in at the factory connectors.

Do these mount using the factory bolt holes?

Yes. These headlights are designed for direct mounting at factory rocker points — no drilling or frame work required.

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

Test-fit before committing — verify that the housing sits flush against your fender and that all connectors align. Once installed and wired, returns become complicated. Confirm fitment in person first.
