Motorcycle helmets are, by definition, protective. The Sotera concept from designer Joe Doucet is just more protective than most. Not by adding any additional padding or space-age shell material — it's still made from Kevlar and polycarbonate — but by using the bottom of its 3/4 design to integrate an LED lightbar. Paired with an accelerometer, it turns red when braking, white during acceleration, and off when at rest. No word on when it might make it into production.
