Will this bolt straight into my car without modification?

Yes. This uses factory mounting points — disconnect the OEM connector, unbolt the old unit, and bolt this one in place. No drilling or brackets needed.

Does the bulb come installed?

The assembly ships as a complete housing unit. Confirm bulb and ballast condition before installation; if replacement is needed, source HID bulbs separately to match your existing driver-side setup.

What if my left headlight is different — will these match?

This is a right-side unit only. If you're replacing both sides, order a matching left assembly separately. Mixing OEM and aftermarket housings may create uneven beam patterns.
