NineLeaf's Bike Tail Light combines a super‑bright 5‑in‑1 LED taillight with wireless turn signals, a horn, and an anti‑theft vibration alarm to keep you seen and heard on the road.

Ride confidently in low light or busy urban streets with a compact, USB‑C rechargeable unit that mounts to nearly any bike or e‑scooter. Designed for visibility and convenience, this tail light integrates turn indicators with a tactile click, automatic brake illumination, an adjustable alarm, and a handlebar remote so you can signal and sound the horn without unclipping from the grips.

How does the NineLeaf tail light improve visibility at night?

The lamp uses 31 high‑quality LEDs and up to 160 lumens to create a strong rear signature in foggy, rainy, or dark conditions. Multiple steady and flashing modes let you adjust brightness and battery usage based on the ride and ambient light.

• 31 LEDs delivering up to 160LM for clear rear visibility
• Six modes: slow blink, breathing, rapid blink, steady, emergency, off
• Auto ON/OFF in low‑light slow blink/breathing modes to save power
• IP64 rated housing resists rain and dust during rides

What signaling and safety features does it offer while turning and braking?

Left/right turn signals are activated by the wireless remote and include an audible clicking sound to alert both rider and nearby traffic. The unit detects deceleration and triggers a bright brake light for two seconds to make slowing down more obvious to following riders and drivers.

• Wireless remote activates left/right turn indicators with click sound
• Auto brake light engagement for 2 seconds upon deceleration
• Remote‑controllable horn and three selectable horn tones
• Quick, tactile feedback on remote reduces distraction while riding

How does the anti‑theft alarm and horn work?

The built‑in vibration sensor triggers a loud, adjustable alarm (up to 110 dB) if your bike is bumped or lifted. Sensitivity has seven settings so you can choose a light touch or stronger trigger, and the remote can also sound a Horn/bell to locate your bike in crowded areas.

• Vibration alarm up to 110 dB to deter theft and attract attention
• Seven sensitivity levels to match parking conditions
• Three horn sounds selectable from the remote for different alerts
• Remote bell function helps locate your parked bike quickly

How long does the battery last and how is it mounted?

The tail light includes a 3.7V 1500mAh rechargeable battery (USB‑C) that can last up to about 70 hours depending on mode. The package includes three universal brackets plus a remote strap so you can mount it on seat posts, frames, under seats, or on handlebars and e‑scooters.

• Built‑in 1500mAh battery with USB‑C charging up to ~70 hours runtime
• Remote uses replaceable batteries lasting 3–5 years under typical use
• Three mounting brackets fit seat posts, frames (35–60mm pole spacing), under seats
• Universal remote strap fits most handlebar diameters for easy mounting

Who is this for: Cyclists, commuters, and riders who want a single, versatile rear light that combines bright visibility with active signaling and theft protection. It’s well suited to city commuters, e‑bike and scooter users, and anyone who needs clear turn indicators plus audible alerts without rewiring—especially useful for night riders, group commuters, and those parking in shared or busy areas.
