I picked up one this year. I was at Gander and they didn't have anything that was on my list and I felt like spending money, lol. I got the truglo one. I shoot an older, cheap version of the trophy ridge. So I am still trying to keep it from looking like a dang flashlight when I turn it on. I've never needed one in the past, but hey who knows. Typically it would be non-legal shooting hours, but I can see in the thick October timber on an overcast or even rainy day that a little bit more glow would be legal and beneficial to have.
I see I'm going to have to try the felt marker trick on the light.
