Do I need both left and right, or just one?

This is sold as a single unit. If you're replacing a damaged fog light on one side, order one. If you want to refresh both sides, add two to your cart and select left for one, right for the other.

Will this bolt straight into the factory location?

Yes — it's designed as a direct replacement for the OEM fog light. No cutting or modifications needed to the housing or surround.

What about wiring and bulbs?

The assembly connects to your existing fog light harness. You'll need to confirm bulb compatibility with your vehicle's service manual or test-fit before driving.
