No mentioned it here but on some lights, especially near fire houses, you can take advantage of the strobe lights on emergency vehicles. (Of course, this only works at nite.) In my car, if I'm far back enough, I flash the high beams a few times before entering the intersection. If it's strobe triggered, the light will change to green before you get there. If you have a strobing light on your bike, you may be able to achieve the same.
