The PWR Redcap is an attachment designed to mount Knog PWR Rider or PWR Commuter bike lights to your helmet, functioning as a rear light. It provides a 12 lumen narrow rear light beam for day and night visibility and can be programmed using Knog's Modemaker app. The package includes the PWR Red Cap, a helmet mount (compatible with GoPro®), and an adapter. The light is water-resistant and offers programmable modes, with a narrow beam for distance visibility.
