I'm not really knowledgeable on the audi 80, but as I mentioned, all Listers with orange corner lights seem to have 80 B3 lights, while the ones in red, seem to have a red version of them. These also match the 80 B4 avant (but not the saloon).
So I believe they match these in side view (notice the slightly more extended top):

Unfortunately I'm yet to find any close up of a perfect side view from either orange or red corner lights. Here are some other references for reflectors anyway:
1 2 3 4 5 6 7 (the most lateral non-lamp reflector part on the red version seems the same shape as in the older orange)
8 9
