So managed to ease the 8 clips off the lense to body.
A gentle bit of pressue and the lense released from the foam/rubber gasket.
The chrome reflective on one of them was shot, almost cream around the headlight bulb area.
Luckily I had a spare set, lenses were machine polished inside and out.
New set of clips are coming to complete the clean up.
Here they are just awiting the clips.
