emzino said:Can't remember where I heard it but is it true that at night, if you flash your lights at a traffic light while red on approach, it will turn green...
Craigybaby37_A3quattro said:i heard it was something to do with police cars etc with flashing lights that change them to green so its the same principle with a car flashing its lights.
through saying that some it works on and others it doesnt.

timps said:<pedant mode> light does move.
Ess_Three said:I agree..
How else could one, for example, fire a laser beam at the Moon to see how far away it is, if the light beam did not travel to the Moon, reflect off the reflectors left by lunar missions, and be detected back on Earth?
Or how else would laser speed detectors work, if they did not fire a beam of laser light and time how long it takes to return to the unit?
Ess_Three said:Pah! Poor retort...
I thought you were supposed to be an Engineer?
Or is that twice removed on your Mothers side...?
Shades said:If they do change on approach (by any vehicle) it is nothing more than coincidence
mitch78 said:I can't believe you actually admit to that, never mind publishing the fact online!
If you were meant to treat it like a normal junction, there would be give way lines and not traffic lights. Doing something like that is asking to cause an accident, no matter how careful you are. At least a car coming up to a junction would consider that you may not have seen them and could possibly pull out in front of them, but most people just assume that if the lights for them are green, then there is no chance of cars coming through from other directions.
You may find this useful.
jojo said:There's comes a point when common sense provails, when sitting at the said lights for 5 minutes and no traffic around, I'm sure most of us will just 'jump' the light as it were, don't see a problem with that myself, but not telling you to go out and break the law.
emzino said:I thought the cameras on top of the traffic lights (small cameras) were there so if you do jump the lights, you get a nasty letter through the door... so there is no way you can jump the lights. Or have I been told wrong
emzino said:So if there are no cameras on top of the lights then essentially you can drive right through them... wow didn't know that
bowfer said:Not so sure about that.
Where I live, you can be sat at the lights for an absolute age, yet when a bus comes along they will immediately change.
Buses hardly ever have to slow down for these lights, never mind stop.
Whether it's just a case of the sensors being heavily angled in favour of the bus lane or not, christ knows.
An ex bus driver here insists the buses are fitted with 'strobes', whatever he means by that.
It's damned annoying though.
bowfer said:Those road loops are a nightmare too.
They only work if traffic moves over them.
If the traffic is static, they don't register anything 'new' and you'll sit there for an age.
I see it every night, exiting our industrial estate.
auroan said:And the induction loop argument is tross. Tell me how the induction based parking sensor works when picking up a brick wall ? Its nothing to do with iron content, is all to do with how and object alters/influences the magnetic field of the induction loop.
treblesykes said:I once came up to some temporary light on a bridge in the middle of nowhere, It was about 10pm the road was straight no other cars in sight, so I went straight thru on red. A cop car immediately appeared from a little tree sheltered lay-by followed me for about 2 miles then pulled and breath tested me. I passed the test but the cops made me wait while they confirmed my details, more cops arrived and they had a long chin wag while I sat in my car waiting waiting, after about half an hour they let me on my way.
I couldnt kick up a fuss because I didnt want a producer ticket as while waiting in the car I remembered the car was overdue its MOT
ChriS3 said:However, light exists as both electromagetic waves and photons and yet it has no mass. And if you follow the theory of relativity, then if there is no mass then there can be no movement! (Actually, its also the Newtonian theory - force = mass x accelleration)
ChriS3 said:Light doesn't move,
bowfer said:As someone else says, common sense prevails.
If it's two in the morning, I've been sitting there for ages and I can clearly see there's feck all coming, I'm going son.
If you want to sit there, that's up to you.
