How Do I Install Mazda 3 Halo Lights?

Only the most high-end luxury cars hit the road factory installed with what the public has come to know as "halo" lights. These little rings of High Intensity Discharge (HID) light make all the difference in the world between a typical unnoticed passing car and an exotic automobile that turns heads in envy. Even though your Mazda 3 may not have had halo lights preinstalled, you can order custom halo headlights and install them on your car yourself.

  1. 1

    Unscrew the eleven 8mm or Phillips screws from the bottom of the front bumper, and then remove the two Phillips screws next to the hood latch. Remove the two plastic, rubber bumpers with a small flat head screwdriver. Take out the two plastic Phillips clips supporting the mud shield in the front wheel well on each side. Pull the shield back and remove the sole 8mm screw next to the bumper seam. Pull the bumper out until it hangs. Unclip the two hooks attached to the subframe (near the hood latch). Detach the bumper.

  2. 2

    Disconnect the wiring and remove the screws and bolts connecting the old headlights to the vehicle. Test the positive and ground wires of your new headlight by connecting them to the power and ground (positive on the battery and any engine compartment bolt, respectively). Tape the new headlights' ground wires (and blue or white LED wires, if applicable) together. Solder the taped wires, if necessary.

  3. 3

    Use a wire clamp to connect each headlight's wires to the parking light connector's positive and ground wires. Insert both ends of the wires into the wire clamp and press down to connect the wires together.

  4. 4

    Insert the key into the ignition and turn it to the "Run" position. Check to see if the halo lights turn on. If they do, bolt the headlights back on and reattach the bumper.

Tips and warnings

  • Wear latex gloves to avoid getting fingerprints on the headlight bulbs.
