Up here at the marble mine they didn’t have lights at all, other than a few candles. All their flashlights were LED-based. Instead of simple on-off switches, they had buttons you could press multiple times to get different brightness levels or check the batteries or what have you. There must be a little microprocessor inside the unit counting the button presses and deciding what action to take. Those were fried. So the lights didn’t work. Fortunately the moon was full. It was what they used to call a Comanche moon on the Texas frontier, for the warriors of that people had taken advantage of its light to mount nocturnal raids. Rufus was thereby able to hike down from the peak and find his way back to the campfire without turning an ankle. He’d had an idea that he could hot-wire some flashlights by opening them up and soldering wires directly between the battery terminals and the LEDs.
