I have steam Altimeter,Vsi and ASI, and I need to have them illuminated for night flying. The instruments do not have any internal lighting and so I was thinking if anybody has already come up with a solution for lighting instruments. I was thinking of buying some clear perspex cut to fit in between the panel and the instrument face and driling a small hole into the perspex to fit a very bright LED, thus lighing the perspex and in turn lighting the instrument face?????

Thanks Guys
