I was trying to do this tonight. I got as far getting the whole indicator unit out as far as the electric cables would let it but I had trouble getting the lens off. Any tips? Tried a screwdriver along the bottom where it looks like it is held on but the lens was going to crack before it came off I think. I've got am '89 plate C with the recessed bumper if it makes any difference.
EDIT: Ignore me, I'm being stupid.
