The LED traffic signals around here are super noisy electrically. They 

rip up my mobile gear from the AM broadcast band through 2 meters any time
we are close to a traffic light. Some are worse than others. If you can find
out who makes them then avoid that manufacture like the plague.

If you all check, they are using LEDs in traffic signals now by the
thousands.  These are variations of multiple LEDs used in these signals
and  they
are all powered by 115vac thru the traffic controllers.
