Seen here is Matrixx Tactical Stun Flashlight, which packs a punch of 7.5 million volts. Reps for the company say they device is OK with the DOT to carry in the cab of your truck. They also said the best use is for protection at night when walking around truck stops or around your truck while using the flashlight.
The flashlight has an aluminum and polymer body and a rechargeable battery. No license or permit is required to carry, Matrixx says. Below is a brief video demonstration — what do you think? Would you carry one?
