Nothing is waterproof. There are various levels of water "resistance" only.
I used phenoseal to seal the entire lense and end caps and wire hole. I disassembled everything, carefully applied massive quantities and I still had a few get water inside. It was always the wire hole.
When actually installing them on and under the truck, the wire gets pulled, twisted and the seal is broken. (Phenoseal stays pliable, like silicone) and it gets pulled out of the hole. I never saw it until they failed. This is what you get when buying a cheap set of LED lights. Replacements will be Rigid.
Hope this helps.
I always heard that a duck’s ass was waterproof. No?
