The Mazda6 is a mid-size car that has been produced by Mazda since 2002. Eventually, the headlights will burn out on your 2005 Mazda6. Replacing the headlights is simply a matter of changing the bulb. The 2005 Mazda6 uses HB3 bulbs for the high beams and HB7 bulbs for the low beams. Driving with faulty headlights can be very dangerous, so be sure to replace the bulbs as soon as they burn out.

Step 1

Park the Mazda6 on level ground and turn off the engine. Lift the hood and prop it open. Put on the gloves.

Step 2

Remove the retaining screws on the headlight assembly by turning them counterclockwise with a Phillips screwdriver. Pull the assembly out of the vehicle. If replacing the left-side bulbs, make sure to remove the plastic cover off the assembly as well.

Step 3

Remove the electrical connector from the assembly by pulling it from the rear. Pull off the appropriate sealing cover. The larger cover houses the low-beam bulb, and the smaller cover houses the high-beam bulb.

Step 4

Swing the retainer spring out to free the bulb. Remove the bulb from the socket and install a new bulb in its place.

Step 5

Reattach the retainer spring and the sealing cover. Reattach the electrical connector and reinstall the retaining screws. If you replaced the left-side headlight, reattach the plastic cover. Close the hood.
