Can a ‘smart helmet’ prevent bike crashes? Is it worth $200 to find out?

Ding’s creation is billed as “the next-generation helmet.” While there are other bike helmets with lights, including one from Apple, the Lumos’s lights — which are on the front and back — Ding says, are 1,000 lumens, able to produce a beam that can be seen from about 150 to 200 meters.

The lights can signal when a cyclist is turning left or right via a remote that can be attached to the bike. The lights on the back of the helmet flash red when you are braking. They also are rechargeable. And if you have an Apple Watch, you can sync the helmet and use your watch to operate the lights.
