Bicycle riders are extremely vulnerable on the road, and despite many using their hands to signal their intention to turn, two cyclists a day lost their lives in 2013 in the USA. Especially in the dark, hand signals are hard to see, but the bright LEDs on the Lumos helmet? These are unmistakable. Directly integrated into the helmet, the LEDs allow you to signal with the flick of a wireless remote mounted on the handlebar. Additionally, a red triangle remains lit on the back, encouraging motorists to proceed with caution. On the front are white LEDs which also remain lit all the time, making you more visible from the front. And finally, an integrated accelerometer activates as a brake light! The helmet is waterproof, meets many safety certifications, and the batteries are easily rechargeable through USB. If you want your own, you’ll have to pledge $99 on their fully-funded Kickstarter.
