Do I need to buy the bulbs separately?

Yes. This assembly ships without bulbs—you'll transfer your existing ones or source replacements to match your preferred brightness and color temperature.

Will this bolt directly to my car or do I need an adapter?

It bolts directly. Factory mounting points line up—no brackets, adapters, or drilling. Hand-tighten the fasteners and you're done.

Can I install this myself or do I need a shop?

Basic hand tools and 15 minutes. Disconnect the negative battery terminal, unbolt the old unit, unplug the connector, reverse the steps with the new assembly. No special equipment needed.
