This sounds like a something we would all love to do, but probably wouldn't.
According to an Associated Press story, "a man who said he bought a device that let him change traffic lights from red to green has received a $50 ticket on suspicion of interfering with a traffic signal."
The fellow given the ticket said that the device, which he bought on eBay for $100, helped him cut his time driving to work.
He used "a strobe-like device to change traffic signals because he said he ran late to the office frequently.
The AP continutes, "The device, called an Opticon, is similar to what firefighters use to change lights when they respond to emergencies. It emits an infrared pulse that receivers on the traffic lights pick up."
City traffic engineers noticed repeated traffic-light disruptions on certain intersections and noted the same vehicle when light patterns were disrupted.
