I live in Canada (many dark months) and am a woman who knows many women and I've never known anyone to wear a vest with a light on them. I do own a hat with a light that I use when I'm walking to the gym in the dark so that drivers will see me, but so do many of my friends and it doesn't seem to be gendered.

I also fail to see how facial recognition would be analogous to lights in terms of safety or frankly anything else.
