Mountain Bike V-Brake Brake Light Waterproof LED Portable Turn Signal Mini Bicycle Brake Warning Light with Stainless Steel Spring ABS Plastic V-Switch for Wire-Controlled Clamp Wire-Pull Disc Brake V-Type C-Type 2.5cm x 3cm x 1.5cm 7.6g
Mini Bicycle Brake Warning Light with Waterproof Housing and LED Beads

This mini bicycle brake warning light provides a clear visual signal to other road users when you brake, enhancing safety during day or night rides. Designed for simplicity, it has no on/off switch and only lights up when the brake lever is pulled, which also helps conserve battery life. The light is built for wire-controlled clamp and wire-pull disc brake systems in V-type or C-type configurations, and it is not suitable for oil brakes.
Features and Construction

The brake light combines efficient LED technology with a durable mechanical switch for reliable performance over many rides.
Material and Build
The switch mechanism uses a stainless steel elastic spring paired with ABS engineering plastic, chosen for long service life and resilience. The housing is designed to be waterproof, allowing the light to function in rain or wet road conditions. The light measures just 2.5cm tall, 3cm long, and 1.5cm thick, making it compact and lightweight at 7.6g including the battery.
Size and Practical Fit
With a height of 2.5cm and a length of 3cm, the unit fits neatly onto the brake cable or caliper without adding bulk. The low weight of 7.6g ensures it does not affect brake feel or handling. The fixing is simple and requires no additional tools beyond basic screw tightening.
Uses and Placement

This brake light is suited for cyclists who want a simple, automatic brake signal without complicated wiring or charging.
Event or Professional Use
For cycle couriers, club riders, or event marshals, the automatic activation means one less thing to remember when braking in traffic or during group rides. The waterproof design adds reliability in unpredictable weather.
Everyday Home Use
Commuter cyclists benefit from the 50-hour battery life, reducing replacement frequency. The light works on V-brakes and wire-pull disc brakes commonly found on hybrid bikes and mountain bikes, making it a practical upgrade for daily rides.
Benefits and Buying Value

The brake light delivers a simple, low-maintenance way to improve your visibility when slowing down.
Reuse and Low Maintenance
The CR1025 battery can be replaced when exhausted, and the robust switch and waterproof housing mean the unit should last through many seasons of cycling. There are no charging cables or buttons to fail.
Why Choose This Product
Compared to generic bike lights that must be switched on manually, this brake light responds only to braking, which preserves battery life and ensures the signal is exactly when needed. Its compact size and light weight make it easy to install on most V-brake or wire-pull disc brake setups.
