Do these headlights require any wiring modifications to work with my car?

The switchback function operates on factory power without a relay module. Plug directly into your OEM headlight connectors and the turn signal will handle the white-to-amber transition automatically.

Will these fit if I have xenon or factory LED headlights?

Direct replacement for halogen housings only. If your car has factory xenon or LED headlights, mounting compatibility requires verification before purchase — your bulb type doesn't determine fitment, but your housing type does.

Are these street legal?

LED projector headlights are legal in most states, but regulations vary by region. Check your local DOT requirements before installation to confirm compliance in your area.
