Don't want to dirty your hands again on traditional flares? Looking for the Rolls-Royce of roadside safety lighting? Duroflares could be it. The unit is roughly four-inch-square of aluminum with an LED tinted red or blue, are waterproof and can support up to 20,000 pounds. In other words, it would take a loaded semi to crush them.
Powered by a rechargeable lithium ion cell, the Duroflares come in a box that acts as both a charger and the on/off switch: take them out, they come on, plug them back in, they turn off. They're a little on the pricey side at $180, but if you spend a lot of time on the side of the road these might be for you. Follow the jump to see them in action.
