Do I need to buy the right headlight too, or does this come as a pair?

This is the left assembly only. If you need both sides, order the matching right headlight separately. Many builders refresh just one side if the other is still serviceable.

Will this bolt straight onto my car, or do I need adapters?

Mounts at factory points—no adapters or drilling required. Line it up with the OEM bracket and you're done.

Does this come with a bulb and wiring harness?

Assembly ships without bulb or harness. You'll reuse your existing bulb and plug from the old headlight—a straight swap.
