I’m pretty sure all the LEDs are made in China too. It’s a shame – I think LED lighting systems are probably going to be the wave of the future. Since the manufacturing process is so highly automated, labor cost is not much a factor. We should be building them here, and we should be investing in better lighting technology and keeping that technology here.

As for traffic lights, have you noticed that green LEDs seem to have a much higher mortality rate than the red ones? Notice how many green LED go lights are all funky with half the elements burned out, yet you never see that with red ones.
