Will this bolt directly into my car without any modifications?

Yes. This assembly uses factory mounting points and connects to your existing wiring harness. No drilling, cutting, or adapter hardware required—drop-in fit.

Do I need to replace both headlights at the same time?

Not required. This is a left-side-only unit, so you can replace just the damaged side. Pairing it with a matching right-side assembly keeps lighting consistent if both are worn.

Does this come with a bulb?

Bulb is not included. Verify your vehicle's bulb type (H11 or similar) and source separately if your old assembly's bulb isn't salvageable.
