BrakeFree is an ultra-bright smart LED brake light that mounts onto the back of your helmet and has built-in sensors that automatically light up to let other drivers know whenever you’re braking, engine braking, or downshifting. Unlike your bike’s taillight, BrakeFree is at eye level, so it’s easier to see. It’s an additional safety feature—motorcyclists need those—and it requires no wired installation or connected apps.
