Fog light fix

[Andres]

Hi everyone

I bought new fog lights and been thinking how to stop water from damaging them.
I don't know if someone saw this before, but the seal between the plastic glass and body is not water tight at all.
Not sure if this can fix the issue, but hopefully can help others.




On this picture if you look inside the light you can see the fresh silicone that got squeezed on the inside of assembly. That is absolutely pathetic imo.

Well I did this almost two years ago, when I bought some new foglights; though I didn't seal up the actual vents. And so far, not a single sign of condensation

Having said that, does anybody know how long it typically takes new lights to start to show signs of condensation?

Also, I have not used the lights since they were fitted - not sure whether actually using them helps to keep them dry or helps cause condensation. Maybe would depend on the ambient humidity... :idunno:

Good to hear you don't have issues anymore, gives me hope too.
I'd like to think it shouldn't make a difference if you have a tight seal. But if it's not tight, it would draw in fresh air when cooling down and cause the condensation.

Changed mine for brand new Magneti Marelli's mid 2020. As soon as I actually used them in humid conditions, there were (temporarily) signs of condensation again ... However, there is no permanent damage visible just yet (E86 is my daily).

The design just sucks and blinding plates are also an option ...

I just ordered a pair of Magneti Marelli ones yesterday. When they arrive I planned on doing the lense hole drilling that other members have done and found some success with keeping the moisture out. Not sure which method to try now :?

Mine are Magneti Marelli as well. I'm just trying to seal every possible place and put some silicone grease where the bulb seal is. It's a shame to drill a brand new light..

Just a little update. I fitted the light and drove during very heavy rain on motorway and so far not a single drop of water inside
It's definitely worth sealing it, the old light was falling to pieces :|

I posted this on another thread, but incase anyone wants an easy "fix" for shabby fog lights, I drilled them and wrapped mine in light smoke wrap:

I drilled my new ones. Haven’t tested them in wet weather yet (or any weather come to think of it) but if they don’t stand the test of time I’ve future proofed the issue by getting fog light blanks to put in their place
