Why cant I just flash my high beams real fast?
You can flash your high beams real fast – it just wont activate modern optically-based preemption detectors! 3M Opticom detectors (receivers) have advanced circuitry features which are only looking for the very brief flash of a strobe light, with a precisely timed interval between flashes. Headlamp high beams (any headlamps) turn off and on very slowly compared to strobe lights, and controlling the timing of a mechanical switch to precisely set the interval between flashes might be a fun way to exercise, but it is a waste of time if the objective is to activate preemption detectors.
