We have one and we use it as a night light. Thats why we got it actually and its just a bonus that its a thermometer as well. The red light is not too bright, but the yellow is good. Yellow is when the temp is meant to be perfect. Have a look on ebay. I saw one there not long ago for $20 while I was looking for something else. I saw one last week in a baby store and it was $60! so you could get yourself a bargain if there are any on ebay.
