Biking can be dangerous. Drivers don’t know when you are going to hit the brakes or make a sudden turn. It would be much safer if you had a brake light. The Spooklight has a wireless handlebar touchpad and an accelerometer that lights up your brake light when you slow down.
Just like how a car works. The LEDs are super bright, and the lithium polymer battery will keep it working for about 60 hours. The Spooklight easily comes off the bike and charges via USB. And yes it will also charge your gadgets while you’re on the go.
