It appears that my sealer has gone away or has a gap in my headlight so now condensation is getting it. I was gonna tear them apart, but how should i do reseal it? I have silicone sealer that I used for my valve cover gasket, and was wondering if that would work

thanks

 

Butyl rubber, silicone, they all work. search up DIY CTR headlights and that'll tell you how to bake them open
