Cycling helmet with automatic LED brake tail light, available in sizes M and L for head circumferences 54-61cm, constructed from PC shell with imported EPS interior foam for impact protection during road cycling
Cycling Helmet with Automatic LED Brake Tail Light in Sizes M and L

This road cycling helmet is designed to address two key safety concerns for cyclists: impact protection for the head and enhanced visibility to other road users. It integrates an automatic LED brake tail light directly into its design, aiming to make the cyclist more noticeable during low-light conditions or when braking. Constructed from a PC (Polycarbonate) outer shell and an imported EPS (Expanded Polystyrene) foam interior, it follows a common helmet safety structure. Available in two distinct size options (M and L) and two style variants (Style1, Style2), it offers a practical choice for cyclists seeking a helmet that combines a traditional protective role with an active lighting element.
Features and Construction

The helmet's design centres on its dual-function approach to cyclist safety, merging passive protection with active visibility aids.
Material and Build
The build uses a two-material system. The hard outer shell is made from PC (Polycarbonate), a material chosen for its toughness and ability to withstand abrasion. Inside, the helmet features imported EPS (Expanded Polystyrene) foam. This foam liner is the primary component for absorbing and dissipating impact energy in the event of a collision, a standard principle in helmet safety design. The combination aims to provide a structured barrier against impacts.
Size and Practical Fit
A correct fit is crucial for a helmet's protective function. This model is offered in two specific sizes: M and L. The M size is designed for a head circumference measuring between 54 and 58 centimetres, and it fits a head width of 15.5 centimetres or less. The L size accommodates a larger head circumference of 57 to 61 centimetres, fitting a width up to 16.6 centimetres. These measurements allow cyclists to select the size that provides a secure, non-slip fit without being overly tight, ensuring the helmet remains correctly positioned during use.
Uses and Placement
This helmet is intended for use on the road by cyclists, where its integrated features address specific environmental challenges.
Event or Professional Use
For road cyclists, commuters, or club riders, the automatic LED brake light adds a layer of active safety. It functions as a brake tail light, likely illuminating or changing pattern when deceleration is detected, making the cyclist's intentions clearer to following traffic. This can be particularly valuable during group rides, in urban traffic, or on poorly lit roads, where being seen is as important as being protected.
Everyday Home Use
For the everyday cyclist running errands, commuting to work, or enjoying leisure rides, the helmet serves its fundamental purpose of head protection. The choice between Style1 and Style2 offers a degree of personalisation in appearance. Its construction from PC and EPS provides the expected level of protection for general road cycling, while the integrated light removes the need for a separate rear light attachment, offering convenience.
Benefits and Buying Value
The product's value lies in combining two safety devices into one integrated unit, alongside a focus on achieving a proper fit.
Reuse and Low Maintenance
As a single, integrated unit, the helmet with its built-in light is designed for repeated use. Maintenance would involve general cleaning of the helmet shell and ensuring the light's electrical contacts and battery (if applicable) are in working order. The durability of the construction is tied to the stated PC and EPS materials, which are common in helmet manufacturing for their balance of protection and weight.
Why Choose This Product
Cyclists might choose this helmet if they value the convenience and potentially improved aesthetics of an integrated lighting system, eliminating a separate light mount. The clear sizing data (M for 54-58cm, L for 57-61cm) helps buyers make an informed choice to achieve a secure fit, which is the foundation of any helmet's effectiveness. It presents a solution for those seeking to consolidate their safety gear into one core item.
