Do these mount using the factory bolt points?

Yes. These are designed for factory mounting — no drilling or bracket modification required. Installation follows your vehicle's original headlight mounting procedure.

Are the bulbs included with these housings?

Bulbs are not included. You'll need to transfer your existing bulbs from the OEM headlights or source replacements separately. Check your service manual for bulb type and wattage.

Will I need to adjust beam aim after installation?

Projector headlights typically require aim adjustment once installed. Most shops have beam-aiming equipment, or you can adjust horizontally and vertically using the adjustment screws on the housing itself. Proper aim takes 10–15 minutes per side.
