We got what we call the glow bug from ikea, it is in the kids section and it is a rechargable little night light, it looks kind of like a cute little alien thing and it changes from purple to green to blue. DS can turn it on and off himself (3yrs) and being cordless, and small, he can take it any where. I think it must have a little LED bulb in it, it is cold to touch and stays charged for days. its great for middle of the night wake ups. It cost around $25
