Experimented with this the other day and it's pretty darn cool.
Many lighted or light-able meters have orange needles. Examples here are Dosy meter and meter in the Texas Star amp. These needles will LIGHT UP BRIGHT if you hit them with UV light. Think of hitting day glow orange paint with a black light.
UV LEDs will give the meter a nice warm dark purple glow and the needle will light up as if it were internally electrified.
Can get the UV's on ebay or I have a supply here if anybody needs a few.
