Yeah, as already mentioned, Zebralight, and program it the way you want. 2 modes if you want, or just 1. You can decide whatever you want single-click, double-click, or long-press to be, and just set the “sub modes” to be exactly the same so they won’t do anything different.
It takes about 5 minutes to program it the way you want. You only have to do it once, though. And you have a couple of mode groups, if you ever decide you want a different set of modes for something else, though you don’t have use it.
I set up my Zebralights with a couple of custom mode groups: one for indoor use (mostly dim modes), and one for outdoors (a broad range of outputs). One Zebralight I use on my bike, and that’s set up more simple because I mainly just use a couple of modes for it.
