I don't think i explained myself very well to start with.

What i plan ( if poss), is just to swap the wiring/bulbs, so the indicator bulb is in the fog light and what was the indicator lens would be like a side/driving light.I'm not bothered if it's not effective as a light source, i just want it to light up. If what you say is right and there's an orange lens, even in aftermarket crystal lenses it would make it more difficult but not impossible i don't think.
silvertec bulbs are silver but flash orange.
Now I've written this down it seems like a lot of messing about but hey,

I think I'll put it on hold til i can get a look at some lenses at the Leeds show.
cheers anyway.
