The whole looks to small for the size bulb but it's the correct bulb

 

If it came out easy enough, it should go back in.

Have you got a friend or family member that could give it a try ? If not, then a picture sure would help. Follow the link in Don's signature or just put the picture in your gallery(the little camera icon under your name).
We can extract the pic from your gallery.

 

I think we are dealing with either a damaged housing where it is melted to the point where she cannot insert the bulb thru the opening - OR the bulb is the wrong one and will not fit thru the opening of the housing. Dare I ask what the number of the bulb is that you are trying to use?



If the last few suggestions/questions don't help you resolve your problem, I don't think we can help you much further. You might have to swing by a dealer and have them check it out.
