Will this bolt straight in without modification?

Yes. This assembly uses the factory mounting points—no drilling, cutting, or adapter brackets needed. Just unbolt the old unit and bolt this one in.

Does the bulb come installed?

The assembly ships without a bulb. You'll transfer your existing bulb or pick up a replacement at any auto parts store—standard fitment for your model year.

What if I need both headlights replaced?

This is the left side only. Order a right side assembly separately if you're doing a full replacement or want both sides fresh.
