You should signal when you’re on your bike just like you do when you’re driving your car, for safety reasons. But cars aren’t always looking out for hand signals. Make your signals pop with the SeniTurn, the indicator light for riding your bike.

This weird little device slides over your wrist and middle finger putting a light right on the back of your hand. When you lift your hand, it starts flashing drawing the attention of drivers behind you. Even in low light or busy conditions, this will allow those drivers to see you more clearly so that everyone stays safer.

The wearable adjusts to fits a variety of hand sizes. It also has built in SOS and hazard lights for those times when you do have an accident but hopefully they are minor. Easy to use and may end up saving your life. You can get one for $31.29.
