No – absolutely not. The vast majority of traffic signal lights are controlled by inductive loops, which are electromagnets buried just under the road's surface. You can usually see the thin, black lines in the road at intersections. These electromagnets react to the presence of iron – and nothing else. When enough iron is inside the loop, the traffic signal controller box initiates its cycle for the light. Motorcycles, small vehicles, and vehicles raised above the ground (big 4x4s) do not register high enough to cause many lights to cycle. You can get a Signal Sorcerer® traffic light changer (often referred to as a motorcycle traffic light changer) and attach it to your bike and then the inductive loops will detect it. I use them on my motorcycles, and my small truck. I will never be without them on my motorcycles again!

Absolutly not. The stoplights are controled by sensors imbedded in the roadway. Once your vehicle crosses over these sensors a timer is activated to change the light. At some stoplights there is a sensor up by the light that emergency vehicles signal upon approach that turn all the lights red until they clear the intersection, then the light returns to normal operation.

I have heard that before but i believe the light is triggered when a vehicle pulls into the square cut out in the pavement. But I still like to flash my lights at a red light just so other drivers will try it the next time they are at a stop light and this helps keep the myth alive.

Absolutely not. People are just impatient these days. There are metal strips in the road that can sense when cars are at the light. Most systems are up to date, as to where they are programmed to know what day it is, what time of day it is, and when traffic is heaviest during these days. With this it can change the pattern of how frequently the light changes. With the older systems, they're on a set timer. You can flash your light 50 times, and it will change. When it's scheduled to!

No, usually the lights are on timers in the daytime. Some switch to motion sensors (some combined with weight sensors in the pavemnent) after a certain time of day.
I have never seen a stop light that operates on lights.

this only works on construction traffic lights that sometimes uses a light or motion sensor to speed up lights when nothing is coming in the opposite direction. I don't recommend flashing your brights at any intersection as it blinds oncoming drivers and could cause them to run the light causing an accident. They might even run into you...

No It will not cause it to change. The Lights Change based on the weight of the cars at the light. thats why in most cases lights dont change for lightweight motorcycles. And the cyclist has to run the light.

No amount of extra illumination will cause a traffic signal to accelerate through it's cycle. It's on a pre-programmed timer which can only be adjusted by the Dept. of Transportation in your state.

No, they are on timers. Some are radio controlled for emergency vehicles
