Tonight I got rear-ended on the interstate in Seattle (a surprising kick from the rear), and after the trooper arrived, I got out, he asked for my documents, and....started fumbling with his flashlight (maybe a 2-C style Streamlight) in the dark by the roadside. His flashlight didn't work! Of course I whipped out my little Nitecore EX10 with Nichia219A to light up the paperwork. And again after he talked with the other driver and came back with my stuff. Poor guy - but I didn't feel like donating my light to him.
