[quote]QUOTE: <i>Originally posted by Bergie</i> <br /><br />In our area, traditional stop lights lit by bulbs are being replaced by newer assemblies that contain dozens of LEDs (up to 100, I would guess) in place of a single bulb. They are very intense, and from what I've heard, they save the local municipality a lot of money over the course of a year because each uses far less engery. Plus, since the life expectancy is far greater, you also save greatly on maintenance crews who used to be needed to replace burned out bulbs. Those two factors add up to great potential cost savings over the course of time and were probably why we're seeing a move in the new direction, even if it is more costly up front. (And if you've ever been to southeast Wisconsin, you've probably noticed that there's typically 2 stop lights for every 1 that's needed. Some intersections look like an airport runway, so the savings could be huge.) <br /> <br />Anyway, to my question. Does anyone have any knowledge of either these lights, or the LED technology, to know whether these could ever be adapted for railroad signal use? It'd be interesting to know if a new LED signal could be as intense as a traditional bulb-lit type. <br /> <br />I've been pondering this for months, as I wait at stop lights. I've finally taken the time to ask. I hope someone knows. <br /> <br />Bergie <br />[/quote] <br /> <br />i think they are using those on grade crossings too.
