First, you need to learn how to trip the sensor. You will usually see rectangular cut marks in the
pavement where the sensor wires are located. Place your bike (vertically) directly over one of
those cut marks. The light may not change instantly; give it about 30 seconds. If that doesn't
work, try leaning your bike (horizontally) over the center of the loop.
Good answer. Here's a fine point I've learned.
Around here, they put in special bike-sensitive loops at a few intersections. Instead of being just
4 ft x 8 ft rectangles, the visible saw cuts have an additional line down the middle. It looks like
two 2 ft x 8 ft rectangles, immediately adjacent to each other.
I found that these did NOT work if I lined up on the outer line, as usual! I had to be on the center
line - then they detected me very reliably. So that's another thing to watch for.

If the light still won't change, carefully go through the red light. THEN, when you get home, call
or write your local traffic safety department. Explain this dangerous situation, and ask them to
adjust the sensor's sensitivity.
Also a good idea. I've done this with good results. They may eventually get complaints, however,
because when a standard loop is turned up enough to detect a bicycle, it sometimes responds to false
signals caused by vehicles driving by in the opposite direction in the adjacent lane. Apparently a
three ton truck ten feet away looks just like a bicycle right inside the loop.
But I didn't point that out to them. I just asked that it be turned up.
