well i just got my projectors and i have a question.
did all your projectors come with a strip of black rubber all the way across the top of the lense where it meets the housing? It completely covers up the seal between the lens and the housing on top of the silicon seal.

I looked at this an it looks like its specifically put there to assist in keeping water out.

Either way im gonna silicon the rest of it up real good before I install them just to be safe.

 

cobaltcruisin"Damnit, now my driver's side is fogged up real bad. Passenger side is fine.... now what?!"

Mine too, OH I thought i was goin to be the only one with the chromed projectors GUESS not
It only gets fogged up when i go to the car wash.... Now i just Dry clean the car haha. lol

an0malous"did all your projectors come with a strip of black rubber all the way across the top of the lense where it meets the housing? It completely covers up the seal between the lens and the housing on top of the silicon seal."
Yes mine had that too.

 

Mine fog up whenever it rains and then dry out when its dry... I have the black projectors w/ 3 vents on the back, seems to work fine, just you do get crap on the inside when its wet. They always dry out though.

 

i bought some chrome ones and knock on wood.. i havent gotten any foging yet..

 

i skipped most of this **** but y not put some silica bags inside but behind. they are made to keep out moisture. and reseal them as good as you can.

 

thats kinda a good idea aside from the fact they they would probly melt

 

I'm gonna consider doing this if this works good..

 

It's working so far

 

did this to my moms jeep headlights for her the other day. Drill a small hole at the lowest spot possible. not too small not too big. do one thats just big enough for a water droplet to come out of. now doing it just at the bottom wont do anything. you have to do one at the top also or the headlight will keep the water in there due to vacume.

 

I have had to seal mine twice. The first time I used silicone, that worked for about 2 months. The second time I used this stuff called Automotive Goop. That stuff stuck to the plastic a whole lot better than silicone. That was about 3 months ago, so far so good.

 

yea but the halo's already have holes in the back of them so only one hole at the bottom would be neccesary

 

Here is a bulletin from GM about this. I know you have aftermarket lights, but this might help explain whats happening.
I had a 1988 Escort GT that had so much water in the lights I thought about putting fish in them! I drilled drain holes like you did and it pretty much cured it. Never did get all the algae out though.

--------------------------------------------------------------------------------

The following information is being provided to better define the causes of condensation in exterior lamps and includes guidelines for determining the difference between a lamp with a normal atmospheric condition (condensation) and a lamp with a water leak.

Some exterior lamps, such as cornering, turn signal, backup, headlamps or tail lamps may exhibit very small droplets of water, a fine mist or white fog (condensation) on the inside of the lamp lens. This may be more noticeable on lamps with "multi-lens" designs and may be normal during certain weather conditions.

Condensation occurs when the air inside the lamp assembly, through atmospheric changes, reaches the "dew point". When this takes place, the moisture in the air within the lamp assembly condenses, creating a fine mist or white fog on the inside surface of the lamp lens.

Most exterior lamps on General Motors vehicles use a vented design and feature a replaceable bulb assembly. They are designed to remove any accumulated moisture vapor by expelling it through a vent system. The vent system operates at all times, however, it is most effective when the lamps are ON or when the vehicle is in motion. Depending on the size, shape and location of the lamp on the vehicle, and the atmospheric conditions occurring, the amount of time required to clear the lamp may vary from 2 to 6 hours.

Completely sealed headlamp assemblies (sealed beams) are still used on a limited number of models being manufactured today. These lamps require the replacement of the complete lamp assembly if a bulb filament burns out.

Condensation
A Fine Mist or White Fog on the Inside Surface of the Lamp Lens Occurring After a Period of High Humidity
• May be located primarily in the lens corners (near the vents) and SHOULD NOT cover more than half the lens surface.

• The condition should clear of moisture when the vehicle is parked in a dry environment, or when the vehicle is driven with the lights ON.

• A comparison of the equivalent lamp on the opposing side of the vehicle indicates a SIMILAR performance.

If the above conditions are noted, the customer should be advised that replacement of a lamp assembly may not correct this condition.

Water Leak
Numerous & Various Size Drops of Water Collecting on the Inside Surface of the Lamp Lens After the Vehicle Has Been Exposed to Rain or a Car Washing Environment
• A condition that covers more than half the surface of the lamp lens.

• An accumulation of water in the bottom of the lamp assembly.

• A condition that WON'T clear when the vehicle is parked in a dry environment, or when the vehicle is driven with the lights ON.

• A comparison of the equivalent lamp on the opposing side of the vehicle indicates a different performance.

Any of the above conditions would indicate the need to service the lens or lamp assembly.

 

have the projectors fogged up at all?

 

Only when there is a high humidity out, and its wet, but now that I have done this they clear themselves out in low humidity, and will not fog in low humidity

 

I've not had any problem with my projectors fogging when its wet out or anything like that. Only when I wash the car and theres a lot of water hitting them constantly. odd...

 

well i siliconed the hell out of mine right out of the box, and they have been through some brutal alberta winter weather in the last 2 weeks. and not even a hint of fogging.
And ive washed it 3 times since they have been on.

(we have had over 12 inches of snow, and a few days of -30 degrees)

 

Yea, we had 13 inches of snow on December 1st, car was covered, no fogging. I didnt silicone mine either. Interesting. Oh well

 

warm weather and rain make mine fog
cold weather and snow make mine crystal slear

 

yep mine too... exactly! It really pisses me off since they look sooo nice when they are "crystal clear". I get embarrased when they fog all up.
