Smart USB charging brake sensing taillight with COB LED lamp beads provides 60+ lumen brightness in 35x39x58mm aluminum alloy housing for cycling safety, available in black.
Smart USB Charging Brake Sensing Taillight with COB LED and Aluminium Housing

This smart bicycle taillight incorporates brake sensing technology that automatically increases brightness when you slow down, providing enhanced safety during rides in low-light conditions. With multiple lighting patterns including slow flashing, breathing, fast flashing and burst flashing modes, cyclists can choose the best visibility option for their environment. The integrated USB charging capability eliminates the need for disposable batteries, while the 6063 aluminium alloy housing offers durable protection for the internal components. Measuring just 35mm wide, 39mm deep and 58mm high, this compact light delivers over 60 lumens of brightness through its COB LED lamp beads.
Features and Construction

The smart brake sensing taillight combines multiple safety features with durable construction materials. The 6063 aluminium alloy shell provides robust housing that protects the internal electronics from impact and weather exposure. The COB LED technology delivers efficient illumination with minimal power consumption, extending battery life between charges.
Material and Build
Constructed from 6063 aluminium alloy, the housing offers a balance of strength and lightweight properties suitable for bicycle applications. This material choice provides resistance to corrosion while maintaining the compact 35x39x58mm dimensions. The internal components include COB LED lamp beads arranged to maximise light dispersion and visibility from multiple angles.
Size and Practical Fit
With dimensions of 35mm in width, 39mm in depth and 58mm in height, this taillight maintains a compact profile that fits most bicycle seat post configurations. The modest size belies its functionality, housing the 3.7V/350mAh lithium battery, charging circuitry, and LED components within the aluminium shell while delivering over 60 lumens of brightness.
Uses and Placement

Designed primarily for bicycle safety applications, this taillight serves multiple riding scenarios from urban commuting to recreational cycling. The brake sensing feature makes it particularly valuable for traffic-heavy environments where increased visibility during slowing and stopping is crucial for rider safety.
Event or Professional Use
For organised cycling events or professional riding applications, the multiple lighting modes allow cyclists to select appropriate patterns for group riding or race conditions. The fast flashing and burst flashing modes create high-visibility warnings ideal for peloton situations or fast-paced riding where maximum attention from following riders is required.
Everyday Home Use
For daily commuting or recreational cycling, the USB charging capability provides convenience without the ongoing cost of disposable batteries. The brake sensing technology offers automatic brightness adjustment that responds to normal riding patterns, while the slow flashing and breathing modes provide constant visibility without being overly distracting to other road users.
Benefits and Buying Value

This taillight offers practical advantages through its rechargeable design and automatic safety features. The brake sensing technology provides an additional layer of protection without requiring manual adjustment during rides, while the aluminium construction contributes to product longevity.
Reuse and Low Maintenance
The integrated 350mAh lithium battery supports repeated USB charging cycles, eliminating the need for battery replacement and reducing long-term operating costs. The 6063 aluminium alloy housing resists weathering and impact damage better than plastic alternatives, potentially extending the product's usable lifespan with proper care.
Why Choose This Product
This taillight combines multiple safety technologies including brake sensing responsiveness with versatile lighting modes in a compact, durable housing. The USB charging capability adds convenience for regular cyclists, while the aluminium construction offers material advantages over plastic-housed alternatives. The combination of these features addresses core cycling safety needs with practical, reusable technology.
