Btw. I replaced some years ago the blanket with a sleeping bag (warmer + can be folded/compressed better therefore needs less space when stored/hidden in the trunk), and the normal flashlight with another one which is magnetic on one side (for example so that it won't move while mount snow chains).
I keep a Harbor Freight moving blanket in my trunk. It's thick for insulation, and also cheap in case you need to protect your seats after a muddy activity. I also wouldn't feel torn up about laying it down on ice if I need some traction.
My suggestion for the flashlight is to get one that works as a headlamp. The modern LED versions are quite good, going from incredibly bright all the way down to dim but usable for days.
