A small but sturdy metal wire, called the retention clip, holds in place the Mazda 3's halogen headlight bulb. Headlights held in by retention clips are often called retention clip headlights. If the retention clip headlight on your Mazda 3 has burnt out or broken, you can replace it yourself in under 10 minutes for each headlight assembly. Retention clips are cheap and easy to replace, they hold the headlight bulb steady, and they make changing a headlight bulb simple and straightforward.

    Press inward on the metal retention clip to release it. Pull out the headlight bulb.

    Insert the replacement bulb into the headlight assembly. Strap the retention clip over the base of the headlight bulb.

Thread the socket on the rear of the headlight bulb through the hole in the rubber weather shroud. Reattach the wiring harness.
