I do like the NUD chip, the issue is it's SMD (can't solder those) and for 68VDC and a single LED it's over it's power limit anyway. I guess I might have to get that 48W PSU anyway...

BTW. I'm not limited for space, I've got loads:)
This is what you quoted [Those 7seg displays are pretty neat considering the voltage range on them. I'll have to stick with a small LED indicator as I'm tight on space as it is.] This is why I mentioned that ..Clive
