I have a Varia RTL510 taillight and I can't seem to figure out how the flash modes work.
When I first turn on the light by holding down the power button, it is in a solid brightness mode. By short- pressing the power button, it cycles through the brightness modes: from solid, to dim-bright-dim-bright pattern, to flashing pattern.
I set mine to the flashing pattern and take off on my ride. But every time I finish my ride and go to turn off the light, it is in the dim-bright-dim-bright pattern. Does this happen to anyone else? How do I get it to stay on the flashing pattern?
