Does anyone know if the lights with 3-ish hour burn times can be charged in a car?? I am doing the Furnace Creek 508 in October (2 person team), and we will be riding through the night. I will probaby get a light & motion HID, I guess with a spare battery? But then can you recharge in the car?

For my double centuries where I had 1 hour of so of darkness in the morning I used a Serfas LED light that was PHENOMENAL. I cuoldn't believe how much light I got from such a tiny little thing.
