Such as because I just want to hold a flashlight because I like the feel of a well made product, or because it gives me a sense of comfort and security?
Everyday. Day or night, I bring one of the following: D4V2, DT8 or my Nitecore Tiki. My eyesight is not as good as when I was younger, so whenever there is some really fine print I take out my readers and a flashlight. A good light is also handy when trying to find something under your car seat that fell out of your pocket. I just received my Sofirn SC21Pro, once I get Anduril 2 installed, it may replace my Tiki in the rotation.
Ever been in one of those bathrooms with motion activated lights where the sensors are only at the entrance, not over the stalls and with a ridiculously short timer? Regardless of the time of day, I always have a TUP in my pocket and a Tini 2 on my keychain. Before that it was some form of 14500 with a 10440 plus a photon clone on the keychain. You never know for sure if you’re going to be home before dark or get stuck in a pitch black situation. I prefer not to rely on just a phone with a short reach and questionable battery life that I might prefer to save for calling in help.
Maybe when it's daytime and you're outside in broad daylight?
That said, I usually reach for a flashlight when I don't think I need one when it's close to dawn or dusk, and I'm not aware that the sun is slightly up.
