Bingo. Amazon suggested this window-breaker bezel (6 Attack Teeth) along with the mount.....

I'm a huge streamlight fan. Used them for years on patrol, and use them currently for EDC, hunting, fishing, wheeling, etc.

I have a streamlight strion mounted in my cargo area that is connected to the charger plugged into the 12v plug back there.

I tucked the wire best I could and it charges as I'm driving. I also have a drawer/sleeper system back there and the light is mounted for quick reach when I sleep.

It's an old version and about 200 lumens and dims down to about 60, which is good enough for its intended purpose.

I suggest something small like that verus a big bulky flashlight like a mag light. I'm old enough to remember when maglights were the bees knees, but I sadly had to accept there are better options in smaller packages.

I have lost two of those nice and bright LED's flashlights... but my big maglite with after market LED bulb don't get lost easily. It's too big to hide/roll under most stuff.
