Breathing Bicycle Tail Light USB Rechargeable 3 Modes IPX4 Waterproof

Increase your visibility and safety on every ride with a tail light that blends smart design, reliable power options, and a distinctive breathing glow. This Breathing Bicycle Tail Light is built around a compact 62×43×38 mm form factor with a trio of LED beads designed to grab attention from behind, even in challenging weather. Whether you’re cruising city streets at dusk or commuting through drizzle, this light keeps you clearly seen without adding bulk to your bike.

Two power options for dependable, everyday use

Choose the power setup that fits your riding routine:

• Button battery version — uses 2× CR2030 button cells. Lightweight and simple to replace, it delivers a steady, long-lasting 15–21 hours of operation on a single set of batteries. Great for occasional rides or as a backup light for weeks of use between changes.
• USB rechargeable version — built-in rechargeable lithium battery with USB charging. Eliminates disposable batteries and keeps you riding with 12–15 hours of continuous visibility per charge. Ideal for daily commuters and long weekend trips where convenience matters most.

Three lighting modes for every riding scenario

With three distinct lighting modes, you can tailor brightness and attention level to the environment:

• Steady mode for constant rear visibility in calm conditions
• Breathing/pulsing mode to catch the eye in heavy traffic or at intersections
• Flashing/alert mode for high-visibility signaling during group rides or in poor weather

Why this tail light stands out

• Breathing LED effect provides a soft, attention-grabbing pulse that remains readable from a distance without being dazzling, helping drivers gauge your presence more quickly.
• IPX-4 waterproof rating shields the light from splashes and rain, so you can ride confidently in wet conditions without compromising performance.
• Compact, unobtrusive design at 62×43×38 mm, it sits neatly on the rear of most bikes and won’t interfere with gear or seating.
• Easy power options— choose disposable button batteries for flexibility and long idle periods, or a USB rechargeable version for everyday use and reduced waste.
• Three LED beads amplify rear visibility across a wide viewing angle, enhancing safety for you and fellow riders.

Perfect for whom and when

This light is an excellent choice for urban commuters, students, delivery riders, and weekend cyclists who value reliable, visible rear lighting. It excels in low-light environments, foggy mornings, and rainy evenings when every extra second of visibility helps. The dual power approach means you’re not tied to one energy source, giving you flexibility for everyday use or extended trips.

Practical tips to get the most out of your light

• Keep the lens clean and free of dirt to preserve brightness and ensure the breathing effect remains distinct.
• When using the button battery version, check and replace batteries before long rides to avoid mid-journey power loss.
• Charge the USB version before multi-day trips to maximize runtime, and carry a small USB cable as a backup.
• Test all three modes in advance so you’re prepared to switch modes quickly in changing traffic conditions.
