Lenore @ Evil Mad Scientist Labs procures an LED traffic light assembly! Which means we get a very detailed peek inside –

Of course, after we made sure it worked, we promptly took it apart. It is a fabulous object, designed to be used, abused, taken apart, and maybe even fixed, though there is not much to go wrong. Click through for more gory photos and delightful design details.

aah, the power of LEDs in large quantity. Check EMSL for more pics and info – Link

  1. I’ve seen half of these things completely out, I think some idiot designed them with the leds in series, which isnt such a great idea!

  2. UNBELIEVABLE! who would design such a thing? why not put them in parallel? or at least multiple series segments wired in parallel? what a terrible design!, has anyone else seen these things half lit around town? unbelievable

  3. I think we must have different ones here in Aus. Just looking at the first picture I can see they’re in series. And just didn’t make sense at all because I have seen them with one or two individual LEDs dead, but never with huge tracts of LED real estate out.

  4. Actually, wiring LEDs in parallel is a no-no as you’ll increase the odds that they all burn out. Once a couple LEDs go, you’re over-currenting the rest and it spirals from there.

  5. I think led lights are so awesome and I love the way that they are starting to become more and more popluar.
