I had one on my 84 650 nighthawk and it didn't do squat. The best way to trigger a difficult light is to roll through the trigger lines and brake late at the light, trying to roll PAST the trigger, not stopping on it.
Florida law allows a motorist to run a light ONLY after said light has cycled 3 times. You better be able to prove it to the cop, however, chances are he watched the whole thing and shouldn't pull you over.
I have one light that fights me consistantly, and sometimes it just will not budge. I have blown this light right in front of LEO's without an issue. I have also pulled up far enough to allow the vehicle behind me to try to trip the light.
It's a pain in the a&&, but when you run into the same light all the time, you have to complain to the correct government office, and they will come out and take care of it.......... eventually.
