there are three different types of headlight assemblies for a 2001 infiniti qx4. it depends on the production date of your car. does anyone know the difference between these 3 different headlights for this year?? can you use any of them or do you have to get the exact one for the accurate production date?? my production date is 05/01 was wondering if i would be able to use the other two that are also available?
