Moisture in headlights

[Phylodog]

I purchased an HID upgrade kit a few months back for the factory projectors in my 2013. One of my extension cables was missing connector and when I contacted the vendor I was told that the extension was not needed and that I should just run the wires under the rear cap of the housing. I did not feel comfortable pinching the cables so I cut a small opening to run the wires through and it has now allowed condensation to form inside of the headlights.

M inclination is to remove the headlights, bring them in and heat them up in the oven to dry things out. Once they're dried out replace the rear caps and use silicone sealant around the wires to seal things up. Am I on the right track here?

The same thing happened to me, however I solved it a bit different: as ridiculous as it sounds, with really thick duct/Gorilla tape. I let the unit dry out in the Sun, then put everything back. I had drilled a hole in that back panel, but even with the rubber grommet, moisture was getting in. So I covered all around the grommet with the thick tape. That was around April/May, not a hint of condensation since.

Best I figure, I didn't drill the holes perfectly so in turn the grommets didn't seal perfectly.

Sealing it up is probably the answer. Not sure the oven is the best way to dry them out. I dried out my tail lights by setting them open side down on a central heating duct.

Maybe these will help. Also make sure the vent plugs aren't fully pressed in. Defeats their purpose. Tape some silica packs in there too.
