You can choose between a bright or dim steady light, as well as three warning modes: fast flash, slow flash, and breathing light mode. Switching between modes is easy with just one button, allowing you to adjust the lighting according to your movement and road conditions.

The built-in 250 mAh battery provides operation for up to approximately 4 hours in low light mode or about 2.3 hours in high light mode. Charging is done via a micro USB port and takes just 1 hour.

The housing is made of durable polycarbonate (PC) and features an IP65 protection rating, ensuring resistance to splashes, dust, and minor impacts. The BTL05 performs excellently in almost all weather conditions — even in rain or fog. It operates within temperatures from -10°C to 40°C, making it suitable for year-round use.

The elastic support strap allows quick and secure attachment to the seat post or any other part of the bicycle, without the use of tools. With compact dimensions (35 x 38 x 32 mm) and weighing only 23 g, the BTL05 is easy to carry and store.

Thanks to the bright red flashing light, the Superfire BTL05 bicycle light makes your presence noticeable to other road users. Ideal for night cycling or in low-light areas, it provides increased safety and confidence on every ride.
