It might sound impractical to refit an entire town with devices that allow lamps to blink, but Pashkovsky said that most existing LED lights can operate in the blinking mode and that new lamps designed specifically with sky protection in mind would be no costlier than existing LED technology

Yeah, it sounds impractical. Also, I don’t understand how they’d make them all blink in sync, or am I missing something?
