A bright flashlight could be your greatest weapon against an attacker.

Instead of carrying mace or a weapon, an extremely bright flashlight could ward off a mugger just as effectively, user Sanket Shah claims.

"If you have someone approaching you that seems aggressive, in the gravest extreme, a blast of 300+ lumen to the eyes (especially at night) will give you the opportunity to get out," he says. "And suppose you miss-read the situation; no one is really harmed and you can't get in trouble for it."
