Streamlight Anti-Roll Ring for Stinger Flashlights

Keeps my Streamlight Stinger Flashlight from rolling off the counter. I bought a few of these as spares for my duty light. My biggest problem has been losing them. This time I put some silicone in a syringe, put the bumper on the light, then lifted it up in places and put a dab of silicone (using a needle is the easiest way) all the way around it. If I need to ever replace it, I can just cut it off, clean off the silicone and repeat with another. I also had the same problem with the rubber grommet covering the switch and pulled it apart and put some silicone on it and hasn't come off in a year
