(S) Side Repeaters on a Seicento

First time on the forum & there's lots to read.
I have a '99 Seicento Sporting with an Abarth bodykit & I was wanting to change the orange side repeaters to LED ones.
I have read another article on this forum that they twist off, problem is one just turns (the whole assembly), & one doesn't move at all. I can see the assembly through the gap between the door pillar & wing.
I also see that the wiring is protected by a flexible plastic conduit.
Has anybody tried to change the repeaters? If so how easy are they to fit & wire?
Any help gratefully recieved,
Darren.

Yeah the orange cap twists off the holder then the holders kept in place by two lugs on the back, you need to take the inner arch out to get to it which is a bastard to do, if your lucky you might be ablr to get a set of long nosed pliers and a small hand in there to do it.

I have considerably more mods, THAN YOU!

Thanks for your help. If I manage to change the side repeaters without removing the inner wing I'll let you know.

Regards,
Darren.
