I have two Fenix lights that both have 2 buttons, one on/off and a second mode selector.

The LD12 is perfect as a daily although the side/mode button is kinda awkward to use, the main button is perfect though.
My PD35R is a bigger one that’s really bright, but also too big for normal carry, so I only use it for work when it’s too dusty to see. It has 2 buttons on the back, one small one for mode selection and a nice big one to turn it on/off.
