Just driving around town and seeing the condition of many of the LED traffic lights makes me skeptical that all the kinks have been worked out when it comes to creating & manufacturing LED clusters viable for commercial & residential applications. At least 30-40% of the LED upgraded traffic lights around here are either partially flickering or partially out. Some are so dim I find it hard to imagine they meet FHTSA and DOT specs (Ironically it's the red that always has the dim issue as well, and over here, at some rather crazy intersections at that)
