What are the 5 types of bulbs inside each headlight unit on a 2007 XK? Moisture got into my passenger unit and now I have multiple lights out and some in the driver side so I want to order new bulbs all around. LED is preferred but I’m ok with OEM too.

 

If it's anything like mine of the same year the list is in the owners handbook. Page 76 in my (downloaded) copy. Suitable leds can be found on Amazon but be careful with the exterior lights which will probably show errors if leds are simply substituted for the ones from the factory. Good luck.
