Attach a largeish neodynium magnet (like a cow magnet, as a bonus they are coated in plastic so they don't corrode) to your bike frame. It will increase your magnetic signature massively and cause in wire-loop-in-road light controller to "see" you. (note, not all sensors are magnetic, some are weight based or IR based)

law in WA is you wait one full light cycle and you can run the light. So basically 30-45 seconds and if no one is going you go.

And how do you prove that you did after the red light camera catches you?

Same way they do, you ask for the full tape, which you can get. Or you know just go around the wrong way. Anecdotally red light covered cameras seem to be much better maintained as othewise they lose revenue.

Also this is why you have a dash cam.

The red light cameras I've seen trigger when someone approaches a red light without slowing down quickly enough. Sometimes, late at night, I make a game of setting them off on purpose, by waiting til the last minute to brake. They wouldn't fire if you stopped, waited, then continued after determining that the detector hadn't noticed you.
