Pocket Signal Lights for War Zones

When rocket sirens wake you at 2 AM and you need to guide your family to a shelter through darkness, a flashlight won't cut it. You need a dedicated signal light — a device built to flash, strobe, and be seen from 100 meters away. But the market is a mess: clip-on backpack lights are too dim, tactical units are too expensive, and marine beacons are wrong for ground use. This episode breaks down the technology behind multi-color signal lights, why red and blue matter, how candela beats lumens for signaling, and why the ideal pocketable beacon essentially doesn't exist off the shelf. Plus: legal restrictions on red/blue wig-wag patterns, the Purkinje effect, and why military features like IR modes are dead weight for civilians.
