Guys, don't know what is happening here. Didn't have this in the past 5 months. Then changed to the new osram bulbs and now I get the foggy on the bottom half of the lens.

I thought that it was taking the light assembly and bringing it into a warm house to change the bulb which introduced humid air in. So, I took it apart again, and left it in the house for a couple hours. Took off the back housing and let it dry out over night. I did leave the bulbs in though as it didn't appear it was sealed beyond the back housing.

Installed and I still have foggy but a bit worse. Mind you the weather has gotten worse(wet) over the past week though. Any help would be appreciated.

I have a garage, so maybe not the same. Hairdryer? I would run a small heater in front of the headlight face to warm it up. or a trouble light bulb. Get the mass of the light body warm. Make sure it is not too hot. You don't want to melt anything. If you are bringing it into the house, let it acclimatize to the house. It will take a while. Like a day to get all comfy.

My real curiosity is. I noticed there is a venting tube in the assembly. So it must mean that the unit isn't sealed from an air exchange perspective. There should be a difference between water leaking issues and condensation. Once the headlight cools down, the fog disappears (albeit, overnight) so what am I actually drying out then?

Isn't the vent tube allowing air back in? If the air is moist and cold outside. Wouldn't I have the problem again?

Maybe its to do with your new bulbs burning at a lower temperature from the oem bulbs creating condensation ?

OOOHHH that's good. Stop bringing good ideas in.Very strong possibility there!
Are they Halogen to halogen? I would think the temperatures would be about the same. If HID to halogen? Could he do that?

From what I understand he changed HID for HID. Don't believe you can go HID to halogen.

Yup. I switched from what I suspect was oem to osram d2s CBI. Supposed to be up to 20% brighter ( they are... Just amazing). Just under 5k kelvin which is about 700k up from oem. I surely hope it is simply the fact that Vancouver is humid and cold right now.

Yes, the second time, I brought the assembly into the house let it sit for a couple hours. Opened the back housing left the bulbs in and let it sit over night. House was about 70 degrees.

I left the bulbs in as it appeared that one you have the hosing opened it wasn't sealed from the projector(front)!of the assembly.

The issue is that the vent tube isn't properly aligned when you put the light unit back in. I had this problem after the dealer worked on the lights. It's a bit tricky apparently.

As a rule the HEAT/Cool cycling of the atmosphere inside the "bulb" will serve to purge, through the provided vents, any moisture inside. A real problem with aftermarket conversion to LED bulbs.

Hmmm...20% more light might mean less energy lost as HEAT!

Absent also changing the ballast it seems unlikely the new bulbs could produce more light, arc current flow is, MUST BE, fairly tightly regulated.

Increase in above ~4300K typically results in more BLING for oncoming vehicles, not more "human" forward vision.
