With its center mount bar location and simple activation, operating the Nite Ize Inova Swipe To Shine Bike Light is easy, secure and versatile. Mounted with a durable UV resistant elastomer that securely grips to your bike, the STS Bike Light attaches with a quick pull and lock movement right between the handlebars no tools required on nearly any bike. The brilliant LED light is housed in an impact resistant, waterproof polycarbonate bracket, and operates in multiple modes and two colors white or red. It's activated by a quick swipe of the finger across the top of the light swipe once for high steady beam to safely illuminate the path ahead, twice for medium beam, three times for flash mode to make yourself safely visible to others around you. Mount a second Inova STS Bike Light to your seat post and set it to red flash mode to be clearly visible to others from all directions. Simple to remove when you park your bike, the light itself is also easily detached from the base, so you don't have to take the whole thing with you.
