These head lamp range from $20 to $25 and they are awesome for just about anything at night. Camping, fishing, or just fixing a flat at night. Instead of using AA or AAA batteries they use rechargeable lithium and are super bright.
The package comes with everything you need. A wall and car charger, the battery and the head lamp. There are three modes: bright, dim and flashing.
There are a variety of them on Amazon. I have bought 2 and and they have worked great!
