Traffic light activators

[Nagash]

As mentioned above, the simplest method i've found is stop right in that square thing, directly over the centre line of the 'activator' and just give a rev of the engine.

Seems the big spinning pieces of metal create a magnetic force which sets off the lights. It's worked every time for me.

when coming upto the pressure sensors or the magnetic ones just brake late and hard stoppping quikly on the sensors. works for me plus one wheel action is cool and smart!!!

they are not pressure activated

There's a coil in the ground that magnetic objects can induce a current in, which is why magnets (and presumably revving the bike) work.

Wikipedia's page on inductance is violating their own guidelines of "must be able to be understood by a lay person", but here's a good article, including a specific example using traffic lights:

well done nigel!!!!!!!!!

Take note of the exact location and contact the council. They can have the sensitivity of the sensor tweaked so it's more likely to pick up a bike.
You'll need to be very explicit.

There are a couple I run into as well, I just haven't got around to doing anything about it yet.

I've tried the sidestand thing and it hasn't worked for me.

yup by second light change..fuck it ride through them with care..

There is another thread running now on this forum. I posted this message on it:- Tonight on a USA site a poster stated that the only way they could get these loops to work was to attach a magnet to a boot. When over a loop just put your magnetic boot down.
