Do these mount to the factory headlight brackets?

These mount at factory points with no drilling or frame modification required. You'll use your existing mounting hardware to secure them into the headlight cavity.

Will I need a wiring harness to make these work?

Installation requires connection to your vehicle's factory electrical connector. If you're unfamiliar with electrical work, have a shop handle the wiring — it's a quick job but needs to be done right to avoid bulb failure or warning lights.

Can I return these if they don't fit or work?

Headlights are final sale once opened or installed due to safety regulations and sealed optics — make sure fitment and wiring compatibility are confirmed before committing to purchase.
