I'm still learning about my new-to-me 03 XJR and have been seeing some references to headlight washers in this forum. I casually looked at the front of the car and saw no sign of washer jets. Did these come as an option or are the jets well hidden?

 

You'd know if you have them! They stick out of the bumper and have their own chrome cap (Click on my car's picture and you will see), and when you wash the screen you'd hear the 2nd pump working. I don't think you have them.
