I purchased this during a Christmas season a few years ago. It's a bit hard to tell, but it lights up when you switch it on. I checked it a year ago, and it sometimes lit up and sometimes didn't, but I checked it again and it works fine now. Since it's been a while since I purchased it, I ask that only those who understand the possibility of defects purchase it.
