Sorry for the dumb. I haven’t used my light (D4S v1) in quite a while. When I went to use it yesterday, it wouldn’t turn off. It’s stuck on. The only way to get it to turn off is to unscrew the tail cap. Pressing and holding the button or clicking it is doing nothing. Nothing changes (brightness stays the same). Is there some way to reset this light? I don’t know what I did to get it stuck on.
