Hold on to the traffic light electric pole , close your eyes and concentrate. Wait patiently for results in less than a minute.

Note: Traffic lights that are blinking yellow may require extra time. Also, the "green" effect will often wear off in a short while, may require re-processing. Kudos to the "hum" page.
