Thanks for finding this flashlight! I picked one up the other day and it is nice and bright! I am putting mine inside of a stainless steel toothbrush tumbler that I got from Target, lol. I think it will look ok, we will see.
Unfortunately, I made the mistake of trying to run it off of a 7.2V RC car battery pack, since I happen to have two of those going to waste. It lasted about 30 seconds, then poof. You can hear something pretty large rattling around inside of the housing now, so figured a capacitor got hot enough to melt its solder? So sticking with a 6V battery for now!
Since I plan on running a toolbox of some sort on my rear rack, the battery for it will live there. I am glad that the white wire is working out for you! I am not going to mess with it since my bike is finally running really well, but good to know it is an option
Since I do not ride at night, my main use for this light will be added visibility on the road to cars. Like DRLs on cars, so the unfocused beam does not worry me too much.
Thanks again!
