I went through this also... I went to three different dealerships and two FORD dealers told me that FORD Contours didn't have door handles that glowed green when you turned on the lights.
I told him my Mystique did. I even showed him (one was still working). He told me this was not factory. I laughed... I am the original ower... I don't have the brains to do something like this... give me a break.
He suggested I go back to the MERCURY garage where I bought the car and order them.
I have several issues with that place - but went there anyway. They had them in stock... know just what I was talking about. 4 bulbs cost me around $12.00. Sorry, I can't remember the part number.
Call a MERCURY garage... they will know.
