These are EURO spec—can I use them in the US without modification?

EURO spec headlights have a different beam pattern designed for left-hand traffic. You'll need the WR-ADA-H1-TO-9005-B3-E30-EURO adapter to make them DOT-legal for US roads. This is a common swap and worth the investment if you're committed to the EURO look.

Do these come with bulbs?

The projector housings are included. You'll need to source H1 bulbs separately—standard automotive suppliers stock them.

What's the mounting situation—are these plug-and-play?

These are direct-fit assemblies for your vehicle. Before installation, confirm the wiring harness compatibility with your car and test fit to ensure proper alignment and clearance.
