I didn't see any for 1/5th the price. Those were the only ones with the full assembly that I saw. Until I saw them I was just going to get the lens. The ones I have aren't great, I remember the one with the really rusty light socket, RH side I think was about 2/3 full of water when I bought it 15 years ago. It hasn't filled up since but I'd like to get new and coat the mating parts with dielectric grease
I guess I'll find out soon they have already shipped. They did email and ask for a picture of my lights to make sure theirs would fit and I sent them one of the right side similar to the pic of the left side in that ad. They confirmed it was the correct fit.
