Some of my friends say it does but I think that is wrong. I know there are wieght sensors in the road.

No they do not. There are some systems that can be changed by a signal from emergency vehicles, but bright lights ain't it.
The nice thing about hanging around not so bright people is that you look so smart.
And to look smarter, those are not weight sensors. The wire is in a big circle (coil) and the metal from your car induces a bit of current in the coil to tell there is a car there.
Also, when you see a blue dot in the road, it marks the location of a fire hydrant.

Those sensors in the road do not sense weight. They sense metallic content. That is why a motorcycle won't trip them. Flashing your bright lights at the intersection will not get the light to change. In most areas with significant traffic, the lights are timed. Try going just the speed limit, after you've crossed one light green.

Yes it will - but I believe it is illegal. It thinks you are an emergency vehicle - look above the light, if there is a camara looking thing, that is probably the light sensor. I used to live on a cross road of a highway and our light would take forever - I used to flash it all the time to get it to change.

On some previous lighting fixtures it use to have sesors for that with emergency vehicles yet no longer could nonetheless have that if any. It makes use of a magnetic loop contained in the pavement to detect a vehicle or a chain of timers. only relies upon on how set up.

It IS the sensors in the road.
And anyway, the "bright light" concept would only work at night, and they'd be really screwed up during the day with the sunlight and clouds and stuff.

No way, the only way to change them is if you are an emergency vehicle. Otherwise they operate by magnetic impudence sensors embedded in the road surface.

No, flashing your lights at the traffic lights is just a myth.

No.
However, certain emergency vehicles have a device in them (Think fire and rescue) that does make all the lights green for them ... I think they are a certain frequency radar they turn on and BAM!!! Green lights from Bangor to Key West.
All the best.

Of course not. But flashing lights is usually a warning to others that there is a cop nearby.
