Lumen Labs Lumos

The 2017 Lumen Labs Lumos is a road helmet with extra safety features. Its incorporated lighting system spans both the front and rear of the helmet, providing high visibility to drivers both approaching and oncoming. Sensors within the helmet brighten the rear lights on deceleration, warning followers of the slowdown; a wireless, bar-mounted switch allows the wearer to signal turns. The helmet is rechargeable with the included USB cable, providing a solid 2-1/2 hours of light per charge.
A good high-visibility helmet.
