Cycling for many people is more than a passion. But it can be dangerous at times, especially at night with cars not willing to properly share the road.

 The Smart Bicycle Rear Light with Auto Brake Sensing will make cycling at night much more safer with it attached to the rear of your bike. The brackets are super easy to install on your bike’s seat frame and won’t slip or fall with time. The light is easy to remove, rechargeable and of course to operate. Switch between 3 modes of light and turning it on/off via the one button. It’s also waterproof and senses when you brake or accelerate. Don’t go on another night ride again without this Smart Rear Bicycle Light!

Bicycle Rear Strobe Lights

Features :

Rechargeable Battery: Simply unscrew the bike light off its mount and charge via a USB cord. This ensures you get long lasting light and it keeps the weight down.

3 Modes: With a single button, you can switch the light on/off easily. Cycle through the modes via the same button for a flashing light, pulsing light or solid light.

Waterproof And Strong Shell: If in the unfortunate case of an accident, the light is made of a durable plastic and will likely survive. It’s also waterproof for rainy night rides.

Bicycle Rear Safety Light


Ride Safer: Having adequate rear lights at night are crucial for safety while riding. Now your night rides will be super safe and pleasant for you!

Easy Installation: Installing the bracket securely is a quick and simple job. All the parts are included with the product to ensure this.

Q5-Optical Lens: The technology used ensures that cars in even the worst conditions will see you. Old lenses wouldn’t work effectively in fog or heavy rain, whereas Q5 Optical Lenses are designed to ensure you’re always seen on the roads.

    Great tail light

    The Lantern got on time. It is immediately visible that the goods are of high quality: beautiful packaging, the aluminum body of the lantern, the backlight is very pleasant for the eyes, the signal of the brake is Bright is bright Thank you for your efforts. I'll operate the lantern and add a review later.

    honestly this little light is super visible and fantastic. battery life is surprisingly better than expected. for the price vs visibility I highly recommend this little light.

    Safety First

    This is the best attachment I have purchased for my bike. All I need to do is remember to unscrew the light and charge it on my USB adapter every couple of weeks. Easy to install on the seat post or just under the seat. The choice is yours.
