Riding your bike on a daily basis is a great way to stay fit and burn calories. You should get the right tools to stay visible to others on the road though. Lumos can help. This is a smart helmet with brake lights and turn signals to keep you visible. It has red lights at the back that form a triangle and white lights in front. You get to activate the turn signals with a wireless remote. The helmet does have an accelerometer, so it knows when you are slowing down and turns all the rear lights bright solid when you are braking.
Lumos is water resistant and has a rechargeable battery that lasts up to a week. Like what you see? You can find this helmet on Kickstarter.
