Interesting that someone should mention that modern Chryslers use Panelescent lighting. Indeed they do. My friend Bob Haag gave me a panelescent setup off his Sebring? Intrepid? ; the only panelescence on that car is... the shifter lighting ! Anyway, a very very small power supply operates the thing.. I immediately hooked it up to 12 volts and the shifter lighting worked. So I disconnected it and tried it on a '60 speedometer. Unfortunately, way too dim. It DID work, and it did light up the speedo, but very dim... John Hertog Sag Harbor NY
