Fellow CCWers, those of you who run WML - how long have you rocked it? Have you ever used/needed it?

Thinking about maybe adding WML but I don't know I'll ever need it realistically. I have an edc flashlight I carry instead. I figure if the only light I have on me is weapon mounted that could cause some problems in certain scenarios. Just wondering how many of yall out there have one and have used it. I don't often find myself alone outside in the dark and living in a metro suburbs, there really aren't a lot of very dark locations I frequent
