How do I replace the headlight in my 2005 mitsubishi lancer

Probably a quick and straightforward process:
Go to local parts store to get replacement bulb. If it is the type that fits into a holder, continue.........
- Open hood
- Look at back of bad headlight
- Wire will go to Back of light to bulb holder
- Twist holder counter clockwise to remove
- Pull out old bulb
- Insert new bulb
- Reverse rest of process.
Cheers

Hi Andrew,here's a video showing you how to replace the bulb. Parking Light Change 2002 2007 Mitsubishi Lancer 2005 Mitsubishi Lancer ES...

post a pic of the bulb. HID kits vary greatly. Either post a pic, or remove the bulb and the bulb number should be on the base.

replace bulbs with factory wattage bulbs. might have aftermarket bulbs and will set a arror code causing this issue

Remove cover. Disconnect electrical connector. Rotate bulb and remove. Reverse to replace.

I have a 2005 Lexus Rx330 with HID AFS headlight. My passenger side light went out. I thought the bulb burnt out, so I bought a new bulb. After replacing the new bulb, it happened exactly like my old bulb. It light up lightly and then total black out. What's wrong with it? I thought the ballast burnt. I called Lexus dealer and asked for the new ballast/transformer. Surprised me, they don't know what is it. They told me they only know the wiring harness and the socket, but not the ballast ??????? Could you tell me what do I need to replace?

Thanks,

The procedure doesn't call for removing the headlight assembly. It is as follows:
The high beam headlight bulb and the low beam headlight bulb are replaced the same way.

Open the hood. To change the high beam headlight bulb on the passenger’s side, remove the power steering fluid reservoir from its holder by pulling it straight up.

Remove the electrical connector from the bulb by pushing on the tab and pulling the connector down.

Remove the bulb by turning it one quarter turn counterclockwise.

Insert the new bulb into the hole and turn it one-quarter turn clockwise to lock it in place.

Push the electrical connector back onto the bulb. Make sure it is on all the way.

Turn on the headlights to test the new bulb.

If you replaced the high beam headlight bulb on the passenger’s side, reinstall the power steering fluid reservoir.

Hope this helps, but if you are having some specific problem leave a more detailed comment and I will try to help you.

TEST
remove both bulbs from the lamps but leave them on their wires switch on and see if the bulbs are still different brightness if not they the passenger side lamp housing has damaged mirror is dirty or missalined and needs adjustment. if they are different brightness then this may be a earthing problem.

You shouldn't have to remove the entire headlight assembly to change the bulbs; They should either twist out, snap out, or have a spring clip that holds the bulbs in.

there is a nut on the left side of the light on drivers side,just the opposite on passenger side. you will need a deep socket. there are 2 10mm bolts on top of the assy. and on the back is a 10mm nut you will have to remove on order to remove the assy.
