Where to buy LED traffic signals???

[LEDUser]

I'm going to buy a used traffic light off of ebay for fun. However I want LED ball lights. I used google to search but can't find places to by them. I would like one each of 12" R-Y-G ball light

just the thread to bring up the led traffic lights that were installed in my neighborhood several years ago: they are burning out! ..every year a I see a few more leds are out in the same lights.. I see now that about 25% of the leds are out in a few.. what's up with that???

Same here. Some lights here have an entire section of LED's out. I have also seen flickering ones.

After how many years? It could just be normal with 5mm leds since they are working almost 24h/24h. What color is the most burnt out? Red, green or yellow or all of them? Maybe we could get nice statistics with traffic lights since they get a lot of use and abuse due to weather. Here I cannot say since they only changed traffic lights to led about 1 year ago.

well, they could be up to ten years old.. I'll check again and see what colors are most burnt out, but I'm pretty sure it's the green since that's the color it usually is when I drive under it..

Probably due to crappy solder joints... I tell you, it is very difficult to find electronics these days that have a solder joint quality similar to the gear you could get in the 1980s.

All Electronics has used eight-inch red traffic light LED arrays for $25:

I have to wonder how much that has to do with the push for lead-less solder. I understand cold solder joints have been a big problem with the switchover.

First post so hope it turns out OK.

Just wondering what part of the face of the traffic signal the LEDs are failing in? It it at the top of the signal light? Middle? Just random? I don't mean red, yellow or green. I mean at the top of the red, middle of the red etc.

I've spent over a decade full time work on traffic signals (but mostly incandescent and QH lamps) so am pretty familiar with them. Knowing what part of the signal the LED's are failing in is relevant since they do get different levels of heat, direct sunlight etc.

upper half I'd say..here's another clue ; last time, a whole line of (5?6?)leds were blinking/flickering on and off..
