Keeping Warm With a Flashlight

I had this super bright, hot rodded Mini Maglight set up at 7volts in a nylon belt case in my pocket one rainy night outside last week.
I never smelled anything burning. There was no warning. With one "rabbit ear" I could see the light burnt through my cargo pocket seam threads. Then, I noticed the hole in the nylon case it had to burn through first!!
Shooooot - that was close!!
A custom $1.50 glass lens instead of the stock plastic lens is what saved it from some kinda meltdown. And me.

Aluminum shiny reflector cone instead of the chromed plastic stocker.
It's all set up to run bright and flawless -- and it does.
You just can't accidentally turn it on.
