The Energizer Micro Sport headlight was $19.99, but is now down to $4.99 at K-mart. I saw this both in-store and online as well.
These work out great when you are working on a vehicle, need light, but want to keep both hands free.
You could even use it for a kid's halloween costume if you are creative.
It is 37 lumens and here is the description per K-mart.
The Energizer Micro Sport Headlight is slim and lightweight. It has three light modes, high spot, low spot and a rear facing, red safety flasher. Great for all dawn/dusk outdoor activities like hiking, biking, kayaking, etc.
