This $6 headlamp is very useful for a variety of tasks

If you don't have one of these headlamps, now is your chance, because Amazon has it on sale for $6.39. I use it for barbecuing, walking in our no-street-light neighborhood at night, repairs, and even reading in bed (on the lowest of 3 brightness levels). It's lightweight and comfortable, and comes with 3 AAA batteries.
