I know that back in the day the city would place strips along the side of the road to test the weight near the intersection in order to get the street lights to change. Now there are those cameras that are everywhere. Does it measure movement to change the lights? My nephew’s, girlfriends father who was in some special secret branch of service told him that they respond to flashing lights such as strobes in case there is an emergency vehicle needing to get through but I have tried flashing those things and it seems sometimes it works and sometimes it doesn’t. Anyone else think there is any truth to this?

My hubby does the same thing...flashing the lights....it works 8 out of 10 times. If I am by myself, I usually forget about it and just wait the light out.

Its an urban myth. Dont you think everyone on the road would do this if it actually worked?

Near the end, the article contradicted itself by stating that there may be intersections (although not common) that are enabled to sense a very high rate of speed flashing in order to change the light from red to green. That settles it, I am getting strobes for my headlights. j/k.

They are two different pieces of equipment. One is essentially a camera that monitors part of the road looking for movement. The other is a device that does pick up a strobe-like signal (there are various models that work different ways) from emergency vehicles. These are small black contraptions (much smaller then the "camera" you notice often) that look like a tiny birdhouse (IMO). You see them downtown and in the med center primarily, San Antonio does not have as many of them as other cities. While I am no expert, flashing your lights and getting a signal change is most likely a conicidence as these things are a bit more complicated.

Maybe it is just my hubby's "awesome driving skills"...... (I don't want to burst his bubble.....LOL )
