We've had LED signals here in Osaka for 5+ years how and they work very well. Here are some links (in Japanese) with photos showing what they look like:

Red Light, Green Arrow

Pedestrian Crossing

Green, Amber, Red (the amber is actually brighter than it seems in this photo)

I haven't experienced any problems with them and I drive daily here. There is no noticeable flicker and they are a lot brighter than the traditional signals they replaced.

John Kanzius happened upon the discovery accidentally when he tried to desalinate seawater with a radio-frequency generator he developed to treat cancer. He discovered that as long as the salt water was exposed to the radio frequencies, it would burn. The discovery has scientists excited by the prospect of using salt water, the most abundant resource on earth, as a fuel. Rustum Roy, a Penn State University chemist, has held demonstrations at his State College lab to confirm his own observations. The radio frequencies act to weaken the bonds between the elements that make up salt water, releasing the hydrogen, Roy said. Once ignited, the hydrogen will burn as long as it is exposed to the frequencies, he said."
