Owners of other Mitsubishi vehicles such as the Mirage, Lancer Evolution ("Evo"), Outlander, 3000GT, Diamante, Eclipse, Endeavor, Galant, Montero, ASX, Triton L200 and Raider may also find these DIY instructions to be helpful.

The replacement bulb part numbers are as follows: Low Beam # 9006, High Beam # 9005, Front Turn Signal 7440A (also WY21W or 7440NA) and Side Marker # 2827 (or WY5W).

On most Lancer models, no tools are needed to change the low beam bulbs.

You may need a 10mm socket with a 1/4" drive ratchet and a flathead screwdriver to access the high beam and turn signal bulbs.

The Low Beam bulb is located near the center of the assembly closer to the outer edge.

(To access the driver side low beam bulb on Lancer models with the turbocharged engine, you will need to remove the 10mm bolt that secures the relay box in place. For the passenger side on a turbo model, just lift up the engine coolant reservoir.)

Reach in behind the housing and gently pull back the retaining clip on the low beam bulb's electrical connector.

Slide the plug straight off the base of the bulb.

Rotate the old bulb 1/4 turn counterclockwise and pull it straight out of the housing.

If you do get the new bulb dirty, wipe it clean with a paper towel moistened with rubbing alcohol.

Insert the new # 9006 low beam bulb in to the housing and rotate it 1/4 turn clockwise to secure it in place.

The High Beam bulb is located at the center of the headlight housing.

To access the high beam bulb on the passenger side of the vehicle, you'll need to remove the 10mm bolt that holds the windshield wiper fluid filler hose in place.

Loosen the 10mm bolt in the counterclockwise direction and then push back the wiper fluid hose. Set the 10mm bolt aside in a safe place.

Rotate the base of the old high beam bulb 1/4 turn counterclockwise before pulling it straight out of the housing.

Insert the new 9005 bulb in to the housing and rotate it 1/4 turn clockwise to lock it in place.

Replace the black plastic dust cap and rotate it 1/4 turn clockwise to secure it in place.

The Front Turn Signal bulb is located at the inner edge of the headlight housing.

Pry up the center part of each pop rivet with a flathead screwdriver and then remove the entire fastener.

To detach the air intake duct, you'll need to remove the two plastic Phillips head screws.

You don't have to detach the air intake duct if you are just replacing the passenger side front turn signal light bulb.

I would recommend that you pry out these screws and replace them with pop rivet fasteners that are easier to remove in the future.

Pull the old turn signal bulb straight out of the socket and push in a new # 7440A bulb. You may also be able to use the # 7440NA or WY21W bulb.

Lower the plastic radiator cover back in to place.

Re-insert the plastic pop rivets and push down the center part of fastener to secure them in place.

Reach in and rotate the bulb socket 1/4 turn counterclockwise before pulling it straight out of the housing.

If you removed the windshield wiper fluid fill tube, replace the 10mm bolt by turning it clockwise until it is snug.

Test the new bulbs by turning on the headlights, activating the hazard signals and flashing the high beams.
