Sorry - couldn't resist. We got tired of not being able to see Maggie at night so we got her a Pup Light. It is fantastic. It is bright, comes on a nice adjustable clip collar that has a guard so it doesn't get caught in her fur, and the light is angled so it doesn't shine in her eyes. And it helps me to see where I am going. Worth every penny of the $21.95 price tag (I went back and got a second one for Penny as well) and it runs on AAAs for a long time.
