Less Power Need, Brighter, Longer Life Bulbs for CTC

These are specialized bulbs to fit in a CTC panel. They indicate turnout location, signal aspect or occupancy. The originals were incandescent. They burn out after a while and are harder and harder to find. These are drop in replacements that should last a lot longer. They are also brighter and use less power. I tried one of the LED's on a 9-volt battery and it was nice and bright. Color quality is good. If you have a CTC board that needs new lamps, this is the way to go.
