I keep a Brinkmann Rebel LED light on my beds headboard bookcase, as it is a very nice navigational light, and will get me to my Duty Belt, if I need to check out a noise. In the truck, I have a SuperStinger,a Vulcan, and a LiteBox lightbox with their chargers hardwired in. I would always recommend everyone to have at least a Vulcan in the car, for reasons mentioned above, it's charge is always topped off, it's quite bright, and it will last for more than an hour.
Even a three dollar Rayovac flashlight will work fine for the nightstand, provided you check the batteries regularly, but you MUST get a good quality light for the car. You will be glad you spent the extra money, when you get a flat on a rainy October night.
