F31 led headlight condensation

[lynden11]

One of my headlights has significant water beading inside.

Any pointers as to what to check? No obvious cracks on the lense or the bits of the light you can see with the light in situ.

Thanks

Unusual on an F31, what type or lights are they? LED, Halogen etc.

When I had issues with one of my BMW headlights, it was due to the top joints failing underneath the headlight gasket.

Some of this - https://www.granvilleoil.com/prodInfo?pID=48 and new gaskets fixed it

The only way to be sure where the leak is coming from, is to take it out and pressure/smoke test it. You can take them out without dismantling the front end - https://www.youtube.com/watch?v=GWol1fyT0ng
