Bright - Good Battery Life - I used these as a dash light for my car when the instrument panel burned out. I just clipped one to the blinker switch and used it to illuminate the instrument panel at night. I was particularly impressed with the battery life of the included batteries. Considering the crap-tacualar batteries that most companies include in the electronic products these days, The battery life in these are amazing. A couple of times I would forget to turn it off when I would get out of the car and it would be on all night. It still lasted me probably a month per unit (I used one at a time).
