Ran across this online and thought it was kind of interesting. It is suppose to defeat red light and speed cameras. Now we use to have the red light cameras down here in Virginia Beach but the Virginia General Assembly voted to not continue the program. Seems there were some studies that suggested these cameras might be doing more harm than good with accidents actually up on intersections that use the cameras.

Anyway came across this site.

Not sure if it works but I reckon it couldn’t hurt to try it.
