Installing halo projector headlights is fairly simple, but can take a few hours. This is just a general guide for headlights and might vary from your particular set. For all of our headlights, we always recommend professional installation.

Just a few general tips -

1. Wear protective gloves and goggles before working on your vehicle
2. An assistant is helpful when removing the front bumper
3. Put a mat on the floor of your work area to reduce the chances of scratching or harming your lights and/or bumper
4. Do not make direct contact when handling the bulbs or wire assembly until the unit has cooled down. Also avoid any oils on the bulbs.
5. Test the lights prior to installation

Tools and Supplies Required -

1. Diagonal Cutter
2. Ratchet
3. Extension
4. Socket and Combination Wrench
5. Flat head and Philips Screwdriver

Isn't there something about height regulation for those? From control circuitry or sensors. I see this instructable as only generic headlight change tutorial. No offence :)
