The thing with buying a whole assembly is that it is also made out of cheap glass which will eventually break in the near future. Cheaper to buy Lexan at $10 and replace the lens with it. I personally have done this and I didn't even caulk it. No condensation whatsoever. Good luck!Would it just be easier to replace the entire light assembly? I have one cracked lens and found an entire replacement for $50 shipped on Amazon. A bit more money, but worth it to me if it's a pain in the ass to get the lenses apart. I'll be interested to see how it works for you.
