Oklahoma allows you to run a light on a MC after it becomes obvious that the light isn't tripping, and as long as traffic allows it to be done safely.
Magnets will not trip signal lights!  The sensors they use are unaffected by magnetism.
Here's an article I wrote for a statewide publication about that subject:
Most of us have experienced frustration with traffic signals that don’t
trip for motorcycles. The majority of those problems can be solved by
technique rather than wasting money on accessories that don’t work.
There are various means of timing traffic






lights. Some are timed, so they go through a cycle at a set period of
time, regardless of traffic. An example of this is downtown Shawnee on
Main Street, the lights are on timers. The most common is the inductive
loop. The inductive loop is simply a coil of wire embedded in the road's
surface. To install a loop they cut a groove in the road surface, lay a wire in the groove and then
seal it to protect it from the weather. You can often see these big
rectangular loops cut in the pavement. They show up because the compound
they use to seal them in is obvious. Inductive loops work by detecting a change of inductance. They sense the
mass of metal by a change in the inductance, and the inductive loop is
basically an electromagnet.
How do you trip the inductive loop? It’s really pretty simple. When you
stop, be sure you are directly on top of one of the wires. This works
99.9% of the time. and additional trick for ones that aren’t properly
adjusted is to put your side stand down temporarily on top of the wire.
If that doesn’t trip a light on a consistent basis you should notify the
city so the light sensor can be properly adjusted.
What about these "Green Light Trigger” things that are sold at some
motorcycle dealers? Those come under the category of "snake oil”.
Several of the magazines have done actual tests on the product, and they
consist of a small magnet, which is supposed to trip the light. When
Wing World tested these, they had a local signal light which had a
reputation for being stubborn. They tested the light sensor both before
and after installing the Green Light Trigger. It made no difference at
all, so they took one and placed it directly on top of the loop, it
still didn’t work! Motorcycle Consumer News went farther; when they
failed to get it to work, they contacted one of the major manufacturers
of traffic light equipment and spoke to one of their engineers. The
answer was simple and to the point, a small magnet cannot trip a traffic
signal! It is the total mass that trips the inductance loop and a small
magnet lacks the mass to provide that input. Possibly if you added a
900 lb magnet to the bottom of your bike it might just work!
The Green Light Trigger has a set of instructions to tell you how to
make it work, they don’t mention that the technique works even without
the magnet in place. The illustration shows a traditional signal light
sensor pattern. To trip the light simply pull up and stop on top of one
of the wires. I normally use the left wire as shown by the red oval in
the illustration.
