Here’s an interesting gadget that I learned about from the Daily Giz Wiz podcast. It’s the CommuteMate Flameless Flare, a roadside safety device. This has several advantages over traditional safety flares. It uses LEDs and runs on two AAA batteries, so you can’t burn yourself or set your car on fire. There’s a powerful magnet in the base that lets you stick it right on your car if you need to. The Flameless Flare is reusable, and it’s remarkably inexpensive — Amazon.com currently lists it for $4.79.
