The Q3 for bicycles are characterised by their advanced technology and reliability. Equipped with an intelligent stop system that increases the light intensity when braking, they offer not only safety but also comfort during use. With an efficient battery that provides up to 30 hours of operation on a single charge and four different operating modes - constant, long pulsing, short pulsing and fading - these lights are the ideal choice for night-time riding. The robust construction and stylish black design ensure that the light is not only functional but also aesthetically pleasing. The Rockbros Q3 rear lights are therefore an essential accessory for any cyclist who values safety and visibility. Robust and durable construction for long-term use.
