These headlamps are so handy! I like to keep one in my car and I always take one or two camping with me. I am going to order more of them to put around the house in case of a blackout, since for my bug out bag and some for my toolbox! These have adjustable elastic bands for your head and an easy to reach on/off switch so you can use them while they are on your head. These have 5 modes. Low, high, cob/led, strobe, and red emergency flasher. They are water proof and rechargeable. Great headlamps!
