Jim, here's the pics as promised.
Sorry the quality's not great.
LED dash lights. As I say I will add two more for the engine warning lights as soon as I've worked out how to wire them.
I'm relying on the gauges at the moment.
Good idea about the woodstain, I suppose you could also use some form of nail polish too,although I'm not sure if that would affect any plastics involved.
I presume there may be some form of resistor you could add to the wiring,but that's a subject i'm not too familiar with.....
