Features 7 vibrant colors and 9 adjustable light modes, letting you balance eye-catching visibility with personal style. Controlled via one-button operation: hold for 2 seconds to power on/off, short press to cycle modes, with memory function to retain your preferred setting.
Built-in brake sensor automatically doubles the light’s brightness for ~2.5 seconds when braking or slowing down, alerting riders behind you for added safety.
The light auto-sleeps after 30 seconds of stillness or in bright daylight to save power. It auto-wakes on vibration (when riding resumes) or in low-light environments (e.g., tunnels).
Note: Red steady and dual-flash modes disable auto-sleep and light sensor functions.
High-seal design resists rain and splashes, delivering reliable performance in rainy or muddy conditions.
Note: Keep the dust cover closed during use; do not submerge in water.
