LED’s are showing up everywhere. I see them in a lot of traffic lights these days, they last forever and use less power. You see them in a lot of taillights for custom motorcycles and cars and as replacement kits for lots of motorcycles. I haven’t been paying close attention but I wonder how many are showing up in standard production vehicles. Once they get them to the point where they put out enough light, we’ll probably see them in headlights, too. No heat buildup, either. Drag racing Christmas trees even use them. Link via Slashdot.
