This doll head is designed to creep someone out. I used a cheap night light from my local grocery store. Paid around $2 US for it. Eventually I'm going to change the light bulb out for a red one. I included a post to help with painting the doll head

UPDATE: Since it's Christmas I found red bulbs to use. I got 5 watt bulbs at Wal-Mart cheap. The doll head is slightly hotter with the different bulb. Still is safe. Trying to find the print time to do a skull night light cover.
