Hello all, i have a 30,000 mah battery that i use to record front and rear facing HD cameras, and inbetween the 2 is a usb on/off switch. So i have one more plug in the battery pack that i could use and i also have one more usb power switch, so i was thinking i could power a light. But my main 1000 lumen bike light will not automatically turn on when it gets the power, so im wondering if anyone knows of any light that would do that? I mainly want a very bright, over 1000 lumen or around that. I will be using this mainly to ride at night or early morning on the road when i bike commute or run errands.
