Golf mk1 Crystal Tail lights

Hello everyone!

Currently I am working on my Golf mk1. So after buying new wheels, a front grill with 4 lights and few more things, I thought buying crystal tail lights to replace my stock tail lights. The crystal one are from Dectane.
Has anyone experience with them? Are they any good? To they tend to get yellow or foggy after a while? 

I have these for sale at the moment they aren't clear but look real cool
let me know if your interested

I won't lie, they look amazing, but my Golf is from 1982, so they won't fit.
Could you tell me did you had any problems with them, any issues?

Btw, these are the one's I'm trying to buy:

no issues fit well I have a 1984 cab didn't know there was any difference to the lights
the cars black  so looked a bit too plain at the rear
the lights your after look good
best of luck
