Multi-use LED safety band By day, it's a mild-mannered pant strap but when the sun goes down it transforms into the BRT Strap! The BRT stands for BRIGHT and our little LED safety band can be used as a pant strap, arm band or dog collar. Strap it to anything and you'll be sure to get noticed whether you're on your bike, out for a jog or taking Rover for an evening stroll.
