I was at Lowes this weekend and found battery operated light sets (10 LED lights) on sale for $4.50. They would make great hammock lights for hammock camping. The lights are different colors and flash seperately, they do not all light at once. There is even a sensor that responds to noise or voice to make the lights flash only when there is noise. They run off of three AA batteries.
Now you can just yell and your hammock lights will light to let you know where your stealth hammock is.
The lights were located up by the cash register.
