Found a solution to fogging aftermarket headlights

I got these 50w hid projector headlights from ebay to replace my old ones of my 05 Tacoma. I installed them and they looked great. This was early January and here in Canada we have snow freezing rain and -35C weather. After a couple of days I started to get some fogging inside the lens (see picture one). I thought it would go away when I had the lights on for a while but no it just got worse. I took them off and hair blowed the inside until dry then silicone the whole seem between the lens and the housing. It was better but it started again. I did some research on the net and found out a lot of people had the same problem. Some people even drilled some small hole in the font bottom to rectify the problem. I wasn't ready to go that far so I thought about it for a couple of weeks and came up with a plan. The reason they fog inside is that the interior temperature is different than the outside. One thing was that the headlight has 4 white led peanut bulb between the park light and the orange daylight bulb. This is the bottom area of the headlight and this is mostly where the fogging happened. I decided to replace the 4 leds in each headlight by 4 regular orange peanut bulbs (same as the park lights, just take out and replace). By doing this those little light bulbs produce heat compare to no heat from the leds. This might be enough to fix the problem but I went one step further by removing the 2 plugs covering the vent holes behind each headlights. I went to Canadian Tire and bought 2 feet of black tubing the same size as the plug. I also got 4 x 90s of pvc pipe and some glue. If you look at the photos you can see what I did.I replaced those caps on all 4 vents by 4 pipe tubes like the bottom photo. This way it let cold air inside at the bottom and hot air out at the top. The solution is to seal the front so no water gets in and let the inside breath. You then have a fog free headlight. I have this set up for over 3 weeks now, went to the car wash a few time and we had crazy weather from warm to cold to warm again and not a trace of moisture. I hope this helps some people out there because I know I was getting really frustrated about the fogging issue and there was no solutions out there. Please note that pictures were taken with park lights only.

Clever.

Have you verified that it works?

 

OR, you could just apply a silicone bead to the gap between the housing and the lens. I like your idea though.

 

Good job. Keep us posted on the long term performance. How is the light output on those projectors?

 

Amazing on the output. I have the 6000 which are the whitest light. I might have to lower the adjustment because some people who are driving cars (lower to the ground) are flashing me. I feel a lot safer driving at night.

 

I forgot to say that in my message but I tried that the first time and it did not help.

 

Bought some bhlm lights off eBay (revotec ones since everyone said they were the best) and one just started fogging up last week. I even ran silicone around the edge of each light before install. Guess I gotta figure something else out. Might give this a shot....
