There are three types of ballasts for 03-06 Navigator. Make sure this one matches the one on your headlight! Outer ballast housing is not included, you`ll have to use your existing ballast housing in order to install it on the headlight or glue it to the headlight housing.
Fits 2003-2006 Lincoln Navigator with the same ballast as in the pictures 3-5!
Will not fit all Navigators!
Tested and is in great working condition!
