Do these mount using the factory headlight locations?

Yes. These are designed to use the existing factory mounting points on your vehicle. No drilling, brackets, or frame modification required—they bolt in where your OEM lights sit.

Do the bulbs come installed?

Bulbs are not included. You'll transfer your existing bulbs from the factory headlights, or source replacements separately based on your bulb type.

Will I need to adjust the headlight aim after installation?

After mounting, it's a good idea to get the beam pattern checked at a shop or perform a quick DIY aim test. Proper headlight alignment ensures safe visibility and avoids blinding oncoming traffic.
