Wow, sounds like that really gummed up the works for everybody! Personally, for light, I used a little halogen flashlight that I got from my father-in-law as a stocking stuffer some years back. It's small, but the light is powerful and lasts a while. I might suggest one of those, too. Might be good to throw in the glove compartment.
I do have a car charger for my cell phone, but the problem was that I was never in my car long enough to charge it very much. I ended up having to take my phone to work and charge it there.
