After quite a bit of head scratching and prototyping I've managed to fit these to replace my Caterham fog and reverse lights. These are much brighter and in my opinion look much better that the original rectangular ones. I managed to use the existing holes, I did drill out the rivnuts.
Mounted them in HOU1, extended the electrics from either side and changed the 2 pin econoseals to 3 pins. Trimmed with TRMU1.
Small gripe is that the seal around the cable as it exits the unit does not sustain much moving about - I've resealed with hot glue.
