Bontrager Flare RT Rear Light The new Bontrager Flare RT Rear Light represents 3 years of microstudies to fine-tune the rear light beam focus, flash, lumen output, orientation and even the LED colour. Flare RT’s flash pattern now features an even more powerful 90 Lumen max burst in its interruptive flash pattern to be better noticed by other users of the road - visible from over 2 km away. Connect the Flare RT to your Garmin Edge computer and the Bontrager Light Control App for battery status and control. Be seen in daylight and in the dark with the Bontrager Flare RT Rear Light. Outputting a maximum of 90 lumens, the battery will last a claimed 6-hours of continuous use. This second version is lighter and smaller than its predecessor yet packs more battery life and lumens. It includes a quick connect bracket that’s offset for proper orientation on an angled seatpost.
