I installed a 6-12764 in 1999 and it has been operating trouble free for many years. Recently I noticed that the red and green lights are fading to the point where they are just about clear. When I tried to change the lights, the bulbs had fused themselves to the bulb cover. I know now that I had the voltage too high for those lights. It should be around 12V and I had my ZW all the way up to 16V.
The problem I am having is that I cannot find the red and green colored light bulbs. I can find the clear bulbs but the red and green do not seem to be available. I was able to find some years ago at a train show but not lately. Does anyone know of a source for the red and green bulbs?
