Traffic light trips ..... don't like V-Stroms.

Does anybodyhere actually know a bit about those light trip devises burried under the asphalt in turn lanes?

Anybody ever actually seen one .... maybe while it's was being installed? (Or put one in?)

Is it a "blanket" that actually fills the entire rectangular area we see cut out in the asphalt?

Does it work on weight principle or magnetic attraction and does your DL reliably "trip" these devise?

My DL either is very light weight or it has little ferrous metal down low under the engine.

I might have to sell this bike.... my 1250 Bandit is a porker but it does have that advantage over the DL. He-he, JK.

Most are magnetic, and you're right your bike doesn't have enough metal to do the job.

You can buy rare-earth magnets that will trip them that attach to the underside of your bike. Sometimes putting the kick stand will trip them, but IMHO that's a dangerous move to be out of gear with your stand down at a light (if someone rolls up on you).

I just wait and go through if it's clear (legal in many states).

Never met a dog I didn't like, a machine I couldn't break, or a woman I couldn't tick off.

I have a powerful magnet in attached to my engine / stump guard. I guess it works, as the lights always change quicker than they do on my cruiser.

Call your local Dept of Transportation. They need to fix the locations that don't work. It's normally a loop, not a plate, so put the bike over the line in the road, not inside the loop. I've had no luck with magnets. It isn't really just ferrous metals that trip the signal. Getting Around in South Carolina - SCDOT | Traffic Signals and Motorcycles

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

Please vote in the poll on what Strom(s) you have at

Check this out:

HowStuffWorks "How does a traffic light detect that a car has pulled up?"

I second Greywolf. I think he might be the one who initially turned me on to the idea, I just never thought about calling DOT. I did so recently, and they are supposedly sending some people out to check a couple of lights that always hang me up on my way to work.

I also tried putting some strong magnets on my center stand. I didn't help at all.

If I am in that situation and I see a car behind me, I roll my bike forward or off to the side and wave the car behind me to roll up into the "grid". They usually give me a baffled look, but it works! If I am just by myself, I wait a couple minutes or so and then go.

There is one intersection that is the bane of my daily commute. It's part of an otherwise pleasant country lane. Most cars turn right at the light, whereas I need to continue straight on (this distinction is important, as I explain below). When alone, and regardless of lane position, my motorcycle's magnetic signature simply will not trip the inductive loop sensor. This is not surprising. Further, I've read enough anecdotes to conclude that dedicated magnets for this matter are oftentimes a waste of money.

To date, and with no other cars around me, I've treated the aforementioned intersection as a stale red -- i.e., a de facto stop sign -- and proceeded when clear. I don't like doing so, esp. because cars in the perpendicular lanes are able to travel at a higher rate of speed than my lanes can. Their approach speed can be deceiving. If I'm first in line at the light and I see a car approaching from behind in my mirrors, I intentionally move to the right wheel track (if I'm not already there) to prevent them from driving on the narrow shoulder and making a right turn. Said another way, I effectively force them to stop/position their car over the loop, so as to eventually trigger the green light. No one's ever beeped at me or otherwise forced the issue when I do this, thankfully.

The things we do just to ride our ride...

Can't seem to activate sensored traffic lights.
