Be seen

The Register II/Isode II Helmet Vent Light is a simple way to help drivers and other riders see you anytime, but especially in the early morning before the sun comes up, at dusk, or during a nighttime ride. A simple click powers up two LED lights that pump out bright red light, so you can see and be seen.

– Plugs directly into rear vent of helmet, no tools required
– Rated to IP65 for protection against dust, grit and moisture
