[quote]QUOTE: Originally posted by tree68 And as a corrollary question: The highway community has gone into LEDs in a big way for traffic lights. Are the railroads considering a similar move for signals? [/quote] We are having a lot of road construction work around here now. One night on the way home from work I noticed that many of the construction warning signs are now lighted by LEDs. I was going to post about that and also ask about LEDs in the railroad world. I was thinking about the red lights for passenger cars and maybe FREDs. Signals did come into mind too. There are many flashlights available now with a single LED and some of a combination of LEDs. They also come in a variety of colors. [8D]
