Yakalla Rear Bike Tail Light with Turn Signals, 1500mAh USB-C Rechargeable & Anti-Theft Alarm

This compact rear bicycle lamp integrates 31 LEDs (up to 160 lumens), six selectable lighting modes, an electric horn and a motion-activated anti-theft alarm in a USB-C rechargeable housing. Designed for commuters and recreational cyclists, it senses ambient light and braking to switch modes automatically, offers long runtime on its 1500mAh battery and meets IP54 splash-resistance for everyday wet-weather use.

How does this tail light improve visibility during day and night rides?

The Yakalla tail light uses multiple LED behaviors to ensure you’re seen from far and near. Choose a steady beam for continuous presence, flashing modes for greater attention, or turn signals for clear lane-change communication.

• 31 LEDs delivering up to 160 lumens of rear illumination.
• Six light modes: Slow Flashing, Breathing, Fast Blinking, Steady, Emergency, and Turn Signal.
• Bright, distinct turn arrows reduce confusion for drivers and cyclists behind you.

Will it react to braking and changing light conditions automatically?

Yes — the light contains an intelligent sensor that detects sudden deceleration and ambient brightness. In intelligent modes the unit can brighten on braking or switch on in low light, then power down after inactivity to save battery.

• Automatic brake illumination to warn trailing traffic when you slow down.
• Ambient-light sensing turns the lamp on at dusk or in tunnels.
• Auto-shutdown after roughly 30 seconds of inactivity to preserve charge.

What safety and security features protect my bike from theft or interference?

Beyond visibility, this rear light adds an anti-theft layer: motion sensors trigger a loud alarm if the bike is tampered with. The built-in 110 dB alert is designed to draw attention and deter opportunistic theft or handling.

• Motion-activated anti-theft alarm sounding at roughly 110 dB.
• Instant audible alert if the bike is moved or disturbed while locked.
• Quick visual ID from flashing or emergency modes to attract nearby help.

How long does the battery last and how do I recharge it?

The integrated 1500mAh battery supports extended use and is recharged via USB-C for convenience. Runtime varies by mode, but the unit is optimized for long duty cycles so you spend less time charging and more time riding.

• USB-C rechargeable with four-segment battery indicator on the light.
• Up to approximately 70 hours in low-power modes depending on settings.
• LED grid shows charging progress; a steady right-turn indicator means fully charged.

Who is this for: Cyclists who want a compact, multi-functional rear light that combines clear signaling with smart sensors and an anti-theft alarm. It’s suited for urban commuters, night riders and anyone who wants a single USB-rechargeable unit that increases presence, communicates turns and provides audible theft deterrence without adding complex installation steps.
