We like our MIRTs here at Gizmodo. A MIRT—Mobile Infrared Transmitter—is a device used by law enforcement and ambulances to turn red lights green. While it would undoubtedly be fun to possess such a device, getting caught with one will turn your world upside down. Not only can Traffic Control register which car the infrared transmission comes from, but supposedly some city law enforcement vehicles are equipped with MIRT-detecting devices. Of course, you could always drop a few bucks (or 400) on the Stealth EVP and be immune to all detections, but hey, we re all honest citizens here, right?
