Q1 Ultra Colorful Tail Light IPX6

7-Color Dazzling Light & 9 Customizable Modes 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. Smart Brake Sensor & Enhanced Safety 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. Smart Vibration/Light Sensors (Auto Sleep/Wake) 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. IPX6 All-Weather Waterproofing 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.
