I work as a patrolman, and I can't imagine my shifts without this gadget. It's become a must-have in my gear because it provides excellent visibility and allows me to remain visible in any conditions without cluttering my hands. I chose a tactical vest light here. I know for sure that their devices are designed for real-world use. Over time, I've come to the conclusion that it's worth considering only these solutions and avoiding cheap alternatives from Chinese websites that can fail at the most inopportune moments.
