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)
I wonder if there are different specs for LED traffic lights in Canada? Driving around my city I have not seen any flickering clusters and only a few with small missing LED segments. We range from -40 in the winter to the high 80's in the summer so I wonder if the lack of year round high heat gives us better results?
Red signals are the worse ones for bulb life because they are the ones that get the most use in a signal cycle from what I have been told.
Amber gets the least use so I have seen here that when a signal head gets upgraded the Red and Green will be LED and Amber remains a bulb. Only new signal heads are a new complete LED set.
