The Blackburn Dayblazer 125 is a rechargeable rear bicycle light offering several ways to stay visible in daylight and darkness. Its brightest setting is a 125-lumen High Flash mode, while a separate 100-lumen High Steady setting provides continuous light. The compact design can be fitted to a range of bicycle frame shapes, with mounting shims supplied for different seatposts and stays.

There are four modes to suit your route and the time of day. High Steady runs at 100 lumens for approximately 1.5 hours and Low Steady offers 50 lumens for three hours. High Flash provides the maximum 125-lumen output for approximately three hours, while Low Strobe runs at 50 lumens for up to six hours. A simple button cycles the settings, and the light restarts in the last mode used.

The built-in rechargeable battery is charged by USB using the supplied cable. A colour-changing fuel gauge shows approximate charge level, with green, orange and red indicators; IP67 protection guards against dust and wet conditions. The Dayblazer 125 is a useful upgrade for cyclists who want a visible, adaptable standalone rear light for commuting and regular riding.

Suggested Use & Compatibility

A strong rear-light option for urban commuting, road training and cycling in poor visibility. Use the included mount and appropriate shim to attach it securely to a compatible round or aero seatpost, or to a suitable stay. Position the lamp so that it points rearwards and remains clearly visible above the wheel and around luggage.

Use High Steady for continuous rear illumination or choose High Flash when a flashing setting is appropriate. The 125-lumen headline applies only to High Flash: the brightest steady option is 100 lumens. Check the battery colour before riding and use the supplied USB cable to recharge. Pair this rear lamp with a suitable front light and follow UK requirements for cycle lights and reflectors after dark.
