How do you replace the head light bulb on a 2004 Mazda 6?

I have a 2004 Mazda 6 and need to replace the headlight. How do you get the thing out to put the new bulb in? The owner's manual does not explain how to do this.

This is a problem - I had both drivers and passenger bulbs go on me and came at it through the wheel arch. The method is the same for both sides.

Equipment needed

Short handled Phillips screwdriver
2 x Latex gloves - to save scratches and dirty hands

Use 1 glove to save your hands
Lift bonnet to get as much light on the job as you can
Turn wheel in so you can get at wheel arch liner unmolested
Remove the plastic nuts – don’t loose them
Peel back liner – you can now see the back of the lens cover
You may need a torch, I did
Turn cover and pull it away – you can now see back of bulb
Remove clip, noting the way to the comes out, there is a notch on the base of the bulb and the replacement must go in that way

Use clean glove to handle bulb, keep to base of bulb and not the glass

Replace is the reverse of the above

Allow 30-45 mins first time

It depends whether it is the o/s or n/s you either need to take the windscreen washer res out which is simply unscrew 2 bolts on top and lift it out of the way so you can gain acsess to the light unit then its pretty much plain sailing.or you need to remove the fuse box unit on the otherside

The solution for replacement of the Mazda6 dip beam was great, I had to take the wheel off as I couldn't get the last wheel arch liner clip out, even with a very short screwdriver. Once the wheel was off,access to the lamp unit was v. good. Took me about an hour & quarter to complete the job.

Well, low beam bulb on right side can be accessed also from top, there is between headlight unit and windscreen washer tank. It's easy to change, if your hand can fit there, however you can't see anything, just can do it without watching..... so remove rounded cover, remove one cable (there is jut one on H1 bulb) remove steel clip and take out burned bulb..... then put new one, be carefull, and don't touch glass part of the bulb with bare hand, then fasten clip, connect cable and close cover.... that's it
Right side is also possible from top, just need to move chunk of cables, and also can be accessed from top.... it's way faster than do it from bottom (from bumper side)

Hi how can i replace my Mazda ^ 2006 headlight bulb ?

You can open the hood and you should be able to see the headlight compartment, right between your radiator on the front. Most Mazda's have a plastic cover on them. Simply turn the cover or pull it out. The light bulb is inside that compartment. Hope that helps you.

How do you replace a headlight bulb to a 2005 Mazda 3? Manual says you must bring it do the dealer. Is that really necessary?

First of all, the bulb you will need is probably going to be H-7. Just go to the auto parts store and find the bulb that says H-7 on it. Apparently you're not supposed to replace just one bulb. You should replace them both at the same time, so buy two bulbs ($27.00). Also, I needed a Flathead screwdriver and a pair of latex gloves. Don't try to do this at nighttime. You will need plenty of light.

If you're replacing the driver's side light, you'll have to remove a plastic shield from above the light. Not a big deal. Use a Philips head screwdriver and a pair of pliers (gently!). Remove the black plug that goes into the back of the bulb by squeezing the sides and pulling. Then remove the black rubber boot that goes over it. The Flathead screwdriver was helpful getting the boot off.

When removing the silver clip that holds the bulb in, you'll have to push in on the side of the clip closer to the driver's side of the car. (Please note that it is not necessary to unscrew any screws.) It swivels open like a door.

Next, remove the bulb. The bulb is attached to a black adapter thing. Use the Flathead screwdriver to pry that black thing off the bulb. Throw the old bulb in the garbage. Put your latex gloves on and put the new bulb into the black adapter thing. (Remember not to touch the glass part of the bulb with your fingers. It's not good for the bulb and you will decrease its lifespan.)

Put the bulb with the black adapter thing into the headlight. You may have to fiddle with it a little bit. (You're still wearing your latex gloves, right?) It only goes one way. There's a little notch that fits into the ten o'clock position. (Just rotate the bulb in the headlight. You'll see where it fits in.)

Close the silver clip back over the bulb. This part may be challenging. Remember, the bulb should have no wiggle to it when the silver clip is installed correctly. The end of the clip fits deep inside the headlight. Push it in and try and find where it clips in. It might be hard to do. Don't get frustrated- you're almost done.

Put the rubber boot back on. It has to be tight to protect the bulb from water. Then plug in the bulb. Replace the black plastic shield over the driver's side light. Finally, test the light.

Replacing both headlights took me about 60 - 90 minutes.

About a week ago the passenger head light quit, changed bulb nothing. today the drivers side light quit as well. So now I have no headlights. The high beams work great still. Where should I start looking?

First check the fuses located inside the hood or under the dash. If any are burned replace them. If not, then replace both headlight bulbs and try it. If that is not the problem check the dimmer switch. The best and easiest way to find out is to take the car for a trouble code free at most autoparts stores.

05 Mazda 6 I need to replace the headlights

Behind the head lamp you'll see a circular cap with some fins on it. Turn it counter clockwise and then it should come out exposing the back of the bulb. Then you will need to push in and up on an angle to release the metal spring clip that holds the bulb in place. Then you can disconnect the harness to the back of the bulb and then remove the bulb. Do not touch the glass of the bulb when putting in the new one as that will cause the bulb to catastrophically fail

Changing the bulb for a headlight

I guess you refer to the dipped beam headlamp?
If the light is a normal one, not the fancy expensive bright lamp, bluish colour light emitted you should be able to reach it throgh the wheelarch after removing part of the plastic trim.
The cover rotates and can be easily removed.
The there is the usual wire spring loop that hold the lamp in.
The lamp in mine was a standard H1 single filament bulb.
Took about 20 minutes to replace in semi darkness with the aid of a wind-up torch!

Hope this helps.
