thanks so much, this is very helpfulCoco said:Passenger Side:
1) Use a 10 mm socket to remove the two bolts on the radiator overflow bottle. Move the bottle and place it in an upright position between the radiator and the dipstick (if the engine is cold) or on top of the grille by the hood release. You will notice that the overflow rubber tube will lift off the windshield-washer bottle cap. Replace the cap so nothing falls in.
2) On the passenger-side fender you will see a bracket that one of the bolts came from. That too is bolted to the fender with a 10 mm head bolt. Remove the bolt and bracket.
3) You will see a large round cover; this is where the low beam bulb is located. Remove the cover by turning it right/clockwise (as viewed from the outside-front of the car) or by turning it left/counterclockwise (as viewed from inside the car). When you can no longer turn the cover, pull it out.
Note: I found it difficult to align the covers behind the lights. You have to figure out which little square goes where on the lamp assembly. I put a mark on the cover before I took it off and then I put another mark on the lamp assembly, aligned with the mark on the cover, after I turned the cover to remove it. Doing this will make it easy to reinstall the cover.
4) The cover has a rubber gasket inside the will prevent you from completely removing the cover. However, you can pull the cover back a few inches and change the bulb. I suggest that you see how the bulb goes in so it aligns correctly.
5) There is a metal clip that holds in all H1 bulbs. This one is a real pain to get off. On the bottom of the bulb housing you will see a little ring. First push it down (towards the ground), then push it to the left (as viewed from the outside-front of the car). You may want to use a 4" long piece of tape to hold the clip up and out of the way.
6) Put the bulb in and clip it in place.
7) To install the turn-signal and high-beam lights, simply turn each to the right/clockwise (as viewed from the outside-front of the car) or left/counterclockwise (as viewed from inside the car) and pull the bulb out.
8) Put everything back together.
1) Remove the 10 mm bolt that holds the air box down (this is on the gold colored bracket on the driver-side fender).
2) Release the two clips that hold the air-filter box together and remove the filter. You can then lift the top of the air box out of the way.
3) (see pictures) Pull the plastic tube from the under-hood "ram air" assembly towards the front of the car (it will move about 1/4 inch) and then pull the air box and straight out. It takes a little force because it is held in place by two rubber-male shaped plugs that go into holes. Once you have this out, the bulbs are easy to access.
Replacing the air box:
4) Align the air box’s two pointed rubber connectors with their holes and push down hard. Make sure the front air tube is out of the way. One note: there is another intake path at the bottom of the air box. Make sure that the air box is properly aligned with it and the “ram air” intake.
5) After you get the bottom of the air box in, install the bolt on the fender, replace the air filter, and then finish putting everything on.
Note: Total time to remove everything, change the bulbs, and re-install was 15 minutes. I do suggest that after you get the bulbs in and are sure that the round covers are in place correctly (as I mentioned, that was the biggest problem I had) to turn the lights on and make sure they work. I say this because, as you will see, putting the covers on sometimes causes the red wire to disengage from the bulb.
Note: Once you get all the junk out of the way (the air box on the driver’s side and the radiator overflow on the passenger side) you will see a 10 mm bolt right in the middle of the headlight assembly. This is for headlight adjustment.

I am not sure I have seen this. The clip was held in with a screw above the bulb opening. I am not sure how the bottom of the clip was held in, or which end of the clip is top or bottom. The clip has a small loop of metal at end, however, this loop is too small for the screw, and I did not remove the screw completely anyway, only loosened it.5) There is a metal clip that holds in all H1 bulbs.

Yep, I've dealt with that problem on several cars in the past including the Altima.uh oh.. make sure that rubber seal is put back on there correctly seen many many fogged up altima headlights lately
