The Sigma Blaze tail light is the first Sigma tail light with a brake light function, for use both during the day and at night. Its integrated brightness sensor, which automatically activates the headlight in low light conditions, provides a plus in safety. Its long ignition duration. An integrated accelerometer recognises each braking and signals it to all other vehicles. In day mode, the three LEDs in the tail light come on every time you brake. In night mode, the upper LED is always on and the two lower LEDs also light up when braking. The brightness sensor automatically switches the rear light on and off according to the ambient light conditions, if desired. This saves battery power and is ideal, for example, when passing through tunnels or very narrow forest areas. The BLAZE tail light has a built-in battery that can be recharged through the micro USB port, which can be done on any PC. With the included micro USB cable, the tail light is fully recharged in 3 hours. A battery and charge indicator indicates when the battery level is critical and when the tail light is fully charged.
