I have multiple headlights, but my 2 main ones are my petzl tikka+ and for about 40 years a tiny little Black Diamond Neo, sadly my BD died after one too many dunkings and they stopped making them about 25 years ago, so now my backup is a Dewalt one with about a half dozen too many features, all I want is high, low, and off but it seems everybody is designing them with a crapload of other functions- I don't need 6 levels of brightness, a dozen different flashing patterns (one I had had an auto sos function)and all the colours of the rainbow...
I also don't like rechargeable lights for the simple reason that I need light NOW, not after several hours of charging. my power bank already is able to recharge 4 AA's or AAA's and the solar panel on it recharges them in about 6-8 hours, or the internal battery does it in 2. I can always charge up a set and keep them in my pocket and swap them out out in a few seconds. Being a 4 season camper and former contractor, all my lights get a heavy workout and the cheaper ones just don't cut it. I also have a box of old 3 for $10 ones that I used to lend out to kids- one or two of them could invariably be counted on to forget any light source
