Power to light red LEDs seems to not draw a lot of power, so batteries last quite a while..

though My B&M toplight LineTech, wired rack mounted taillight is nicely bright and its capacitor stand light keeps it on for plenty of time at stop lights..


Busch & Müller Rear Light Toplight View uses 2 line tech lens lines , so may be even Brighter.
