Exclamation Triggering Inductive Loop traffic light systems with Motorcycles

Figured I'd start a new topic on this as it's been brought up in the past.

If you've ever been stuck at a red light for an extended amount of time waiting on a green, it's most likely because the inductive loop system used for traffic lights has difficulty detecting smaller vehicles. The inductive loop system is basically a metal detector, you drive your car or motorcycle over those rings or squares near the stop lights and a shift in the electromagnetic field tells the light switching system know you're there waiting for the light to change.


Anyhow, there's a really simple way around this, magnets and the positioning of your bike over these inductive loops.


For the magnet, I'd suggest this:


although due to the added weight of this magnet, you might want to search for something a bit smaller, just make sure it's a Neodymium magnet. Once you have your magnet, you'll be mounting it underneath your bike on the frame.

Additional information on how inductive loops work and proper bike positioning and mounting of the magnets can be found here: How to Trigger Green Traffic Lights (with pictures) - wikiHow

Hope this helps!

I hold the starter button for a few seconds. But I've only had problems from one set of lights.

I suppose if it was guaranteed to work every time and if the magnets are not too heavy, I'd consider it. In the absence of both those factors, I'll opt for waiting until it's safe to go and then disobey the signal, since that is a legal alternative in my state. Good information, though. Thanks.

Like taught in the MSF class. Wait 2 lite cycles, if it wont change look and go. Easy and it's free.

I'm jealous! I don't believe that's legal in California where I'm at

Definitely not legal in TX.

You are never allowed to run a red unless perhaps you have to do so to get out of the way of an emergency vehicle.

TX law says you must wait until another car comes up and triggers it.

I will wait a bit, then turn right on red (legal here) and u-turn and get back on track.... though I have run MANY before.... but the only time I've had one NOT trip for me on the weebr was during a torrential downpour... guess the water interfered with things?

cheers,

Mods come on this is getting to be ridiculous! Will someone post a new thread on the same old topic. I mean ****. Put comments in one of the various threads already. Them magnets don't work. This best thing to use is your head and common sense.

That's interesting TX_Dj, I don't believe water plays a part in that though because if that were the case, traffic here in L.A would be a nightmare when it rains. Wait a minute... LA traffic is horrible all of the time! I guess I'll have to pay better attention to that next time it rains.


Anyhow, the magnet trick definitely works, my small 02 honda civic SI hb (ep3) used to have issues triggering the light switch. After I installed a magnet underneath my car, I've yet to have an issue. IMO it's a cheap and easy fix for motorcycles as well.

Garblicks, the magnet trick does work, perhaps not in your state \ area, but here in California, it works quite well actually.

Also, was just trying to be helpful, I didn't see any previous threads on this, my apologizes if I missed an old thread on this, (still new to these forums). Thanks for your feedback though
