I mounted it on my bike and so far it seems to be working well.

 chukarboy Posted:

Smaller than I envisioned when I ordered. That being said, it is a powerful magnet that attached easily and securely to the underside of my Yamaha Vstar 1100 using the attached two sided tape. I took the bike for an early morning Sunday drive with little other vehicle traffic. All the lights that I solo stopped at triggered as they would have if I had been driving an automobile. I can't ask for more than that.

 jcarilli Posted:

Seems to work but then again sometimes not. Maybe I need a 2nd one.

 mtbowhunter Posted:

easy install works on some stop signals. It must have to do with the style of traffic light trigger they have installed in the asphalt.

 FrankRoxx Posted:

I love it.I can stop at a red light and get the green arrow every time.Also,it"s easy to hide it so no one can see it.I also bought a second one for my other bike.Thanks J&P Cycles.

 Katibug37 Posted:

 jebsoe Posted:

 heyhdron Posted:

 tanker8tim Posted:

Eazy to mount.

 LeeGVStar1100 Posted:

works good, every bike should have one

 oldschoolxlch Posted:

Works as promised.

 CkMate Posted:

I Have notice no differance in the traffic lights that have always given me trouble around town. Nothing more than a weak magnet. Could have bought a more powerful magnet and glued it to my frame and paid less.

 67sprint Posted:

Works very well.Quick easy installation.

 zumbusmom Posted:

Great product! So far, it has worked on every traffic light I have encountered, including one particularly stubborn light that I have to pass on the way to work at 11:40pm. With no traffic that late, I had been forced, on several occasions, to run the light. I have already recommended this device to a couple of friends at work. Nice product.

 dalescruggs Posted:

Haven't had it long enough to tell for sure, I think it works more often than not.

 1736Jerry Posted:

I mounted this on my 1999 Honda Valkyrie Cruiser with no discernible benefit. I see no difference at intersections that have been a problem for me. I mounted the trigger on the subframe directly behind the engine. The Valkyrie sits higher than some bikes. The lower mounting point would have been on the aluminum bottom pan of the engine? The instructions said subframe. This was a wast of $25.

 bgannon Posted:

works some of the time

 Dragon07 Posted:

Works with most lights.Satisfied

 guerrerojp Posted:

Installed as directed, however I did not get any good results. Still got stuck on a traffic light.

 mark2804 Posted:

works pretty good but it really depends on the part of town, but hey it's easy to install and gives some relief to the long lights

 3jesster3 Posted:

After installation, I have not noticed any difference. A traffic signal near my home still will not trigger when my bike passes over. Yes, I installed according to directions to the lowest point on the frame away from major electrics.

 na7a Posted:

Seems to work ok but not a 100% sure it works all the time.

 rlockyer Posted:

Awesome product. 3 local signals that have never tripped for my 800-pound cruiser now function properly. Worth the $25!

 acedro Posted:

Works without a single failure to date. I am very satisfied. Small size is a plus for mounting.

 bblack4d Posted:

It appears that this product works well on the newer signal devises. It would be easier to mount if there was a contoured pad for flat areas and or tube frames with a notch on each side for zip ties.

 3396712 Posted:

Green Light realy does work and sure beats waiting @ signals for a car to come or taking a chance pulling out Thanks JP!

 okie_sabre Posted:

I have had this product for a few weeks now. I have found it has made a big difference on those light that are stubborn. I think it was a good value and reduces any anxiety about those light that wouldn't trip before.

 kevinsanderson Posted:

Product seems to work as advertised. I am very pleased with my purchase.

 WallyDraigle Posted:

I purchased the GREEN LIGHT TRIGGER HIGH POWER for my Kawasaki KLR 650. In the short time I have had it, I must say, it seems to work! The adhesive used to attach the device was a bit sketchy when I tried to mount it, but a few zip-ties to the rear swingarm seemed to do the trick. It is important to realize this device only is effective on specific traffic lights, it doesn't magically turn all lights green. I was admittedly skeptical, however the device seems to be effective in boosting a cycles magnetic signature, triggering inductive type traffic controls. On the KLR it was difficult to find a suitable mounting point to assure the device was close enough to the sensors, however on a cruiser or sport bike, the ability to get it closer to the street is a definite plus.
