i have a hat with LED lights built into the brim as my primary (need it randomly) light. absolutely LOVE it. has an on/off button on the bill for easy use with an on/off switch on the batteries. switch is shut off until close to dark and then it comes on. this way i dont accidentally hit the button mid day and burn my batteries.

i have a tiny lantern for in the tent(one per tent) (size of a soda can) for that ambient glow for killing the pesky inside the tent skeeters.

i also carry a small 9 bulb led flashlight the size of 2 C batteries that runs off of 3 AAA's in a battery pack. that battery pack also fits into my backup headlamp.
