I finally decided to get around to fixing the condensation issue that my headlight have. I have found on a few different threads for part numbers and some helpful tips, but the pictures are no longer hosted so I thought everything should be in one place.

Tools I used:

A set of 1/4" Torx bits (T30, T25, T20)
Long wobble extension but a regular one should work just fine
1/4" Ratchet
90 Deg Pick/Small flat head screw driver

Consumables:

Something to clean the adjuster screw and surrounding area. (I used brake cleaner)
Some grease/lubricant to help install your new O-Ring. I had some left over silicone spray.
Rags/paper towel

I didn't grab any pictures of me pulling my headlights but it takes all of 10 minutes and you just need a T30 for the headlights x4 screws each one. There is two on top and two behind each light. You take the top two out completely and all you need to do is loosen off the rears and the mounting tabs are slotted. The T25 is for removing the front part of your intake so you can access one of the screws. If you are unsure just start with the driver side one as you don't have to remove anything to access the screws.



Get yourself a clean area to work, I am using my kitchen table with some old towels down so the wife doesn't kill me. My drivers light was already dry but my passenger side one still had standing water droplets inside the lens so it is currently sitting in front of a space heater until it dries. I have removed the turn signal sockets from both lights while they dried/while I worked to make sure all the moisture was out.

Here is the cap to the adjuster screw located on the topside of the housing above the signal light.

Remove the single screw holding down the cover it should be a T20. I say should because my passenger side cover was missing its screw, it had a rock instead. (fun)
On the back side of the cap are 2 plastic gears. Just make sure they car clean and free from sand/rocks.

After cleaning up the area to prevent dirt from falling into the hole we are about to make I used a 90 Deg pick to get under the lip of the adjuster screw. Once I got it started it just pulled up on it slowly with my fingers until it popped free.

Well I guess dirt got down here anyway. Here is the first look of the original O-ring. you can see how it has shrank down and now matched the diameter if the plastic screw.

The small beach were the top of the adjuster sat.

Give everything a clean now. I flipped my headlight upside down to prevent anymore sand from getting into the light.

Here is a shot of the part number/size that I used. I got these at my local Canadian Tire for 0.79 cents each. (one for each headlight)

Here you can see the old and new O-ring side by side.

Not for replacing the actual O-ring, I used my 90 deg pick to lift up on the old O-ring, pull it off the bottom. Now apply a little lubricant of your choice to the new O-ring to help get it in place, but I would avoid anything heavy/sticky that could attract sand/dirt. I had to use a small flat head screwdriver to help get the new O-ring in place.

Now just put everything back together in reverse order and move on to the next one. Finally reinstall your headlights. This took me about 2 hours from start to finish including drying time. I took a few extra pictures if anyone needs them, I just happen to hit my limit of 10 for this post.

So far so good and I haven't had anymore moisture inside my lights.

I hope this help anyone needing to replace these O-rings.
