The Lumos Matrix Urban smart bike helmet works proactively to protect you from impacts during your city commute. With a new RGB dot matrix design, the Lumos Matrix rear lighting panel offers customizable patterns that can help you stand out more clearly on the road. Integrated lights, turn signals, and automatic warning lights (similar to brake lights), offer improved ride safety, night or day. Turn signal indicators can be activated with the included wireless remote or through the Lumos app on both your iPhone and Apple Watch.
