Connecting jumper cables from one car to the other is pretty easy already, but Michelin is making it even easier. The Michelin Smart Jumper Cables are all blue. That’s because you no longer need them to be color coded even.
The circuitry inside knows exactly what is going on and can detect whether a successful complete circuit is achieved or not, and it will let you know via the LED. When a second battery is connected, it will determine the polarity automatically and switch to accomodate. No more worrying about shocks or sparks. Pretty neat.
