I purchased this toy hard hat for my 3-year old daughter because she loved the idea of the light on it.  But the light has never worked.  The replacement bulb doesn't work either.  I don't know if it's poorly designed, poorly built or both.  It's disappointing because the light is the specific reason I ordered this hat.  It's not worth the effort to return it, but if I had it to do again I would just buy a regular toy hard hat.
