Anyone struggling with moisture in their fog lights?

I put new H11 LEDs in my driving lights last summer, recently one went bad already! I looked and there is literally water laying in the lense, not much, but there shouldn’t be any. I’m guessing that the moisture hit the led and ruined it since the fan still works. I looked at the other light and it has moisture in it also and is all fogged up.

Anyone have experience with this? I never had this issue pre LEDs.

 

Very common issue with aftermarket drop-in LED bulbs. Not only do they not perform as well as a good halogen bulb - particularly in a fog light - but the poor manufacturing processes lead to water intrusion and then junk housings. Sorry you had to find out the hard way.

 

I would have a set of like new OEM fog housings if you need to replace

 

Too Stroked, I had no idea this was an issue. They are cheap $35 LEDs that have performed very well, at least until now. I have better Sabre LEDs as headlight replacements and they have been moisture free so far.

I do have the same $35 cheap LEDs in one of my Camrys for 3 years and they have been great. I’m thinking the difference is the Camry headlight being up high in the rad support vs the driving lights low and unprotected in my Tacoma.

 

Had this issue. Ended up having to take my fog lights apart to clean the housings because they became filthy/junk. I’ve read about how it could be due to a poor combination of the fog light housings as well as poor sealing capabilities of select LEDs. It’s better to run Halogens in there because due to there operating temperature they won’t really fog up.

 

It's actually very common - especially with the inexpensive Amazon and eBay LEDs. Many people even recommend swapping the O-rings from halogen bulbs over to the LEDs prior to installation. (But the O-rings are not always the problem.) The fact that you didn't see water intrusion on some of your other bulbs just proves how hit and miss their manufacturing process control is.

I will offer that location does come into play here with your fogs getting a lot more road spray from the back side due to their location. That said, when was the last time you saw an OEM bulb leak water into a housing. (Very rare.)

As for what to do next, I think you'll find saving your current housings to be almost impossible. If you want true high performance fogs, look into a set of Diode Dynamics SS3 fogs. They're designed from the ground up as LED fogs (as opposed to slapping an LED "bulb" into a housing designed for a halogen light source) and work much better.
