Before I buy another I want to check the fuse. Please let me know where this is located.

Because headlamps are considered an essential safety item, regulatory agencies in most of the developed world require that this circuit be protected by self-healing relays rather than fuses. You could try putting the left headlamp bulb in the right-side assembly to validate its health. If you need a bulb, most manufacturers recommend replacing both sides, for intensity and color issues.

 

antdavis1911, the headlights are powered via a fuse box. The fuse box in your XJ also has a bunch of electronic relays built into it. So, you have much more than just a simple fuse box like in older cars. Both headlights are powered from this modules which has a dual fuse input. So, if you look at the fuse box inside the passenger compartment (the central junction box) and find fuses "BCM-3" and "BCM-4", those are for both headlights. They are each a 40 amp fuse.
