My clock light burned out, and I found all the necessary info to change the bulb on the forum, but not in a comprehensive form, so I thought I would post what I did for anyone else who might want to attempt it. BTW- the bulbs are not available through a part store, so have it in hand before you start ( I didn't)

Order the new bulb from jaguar or online. part number LNC5180AA. Ensure you have the code for the radio. disconnect negative battery cable. wait ten minutes. remove veneer trim around speedo instruments by pulling on areas between gauges. (held by clips should pop free) then remove wooden panel around vents and clock. pop free the wooden panel over the airbag.(this is why you disconnect battery) loosen and remove the four screws holding the vent assembly. loosen the deep set screws on the right side of the instrument cluster ( you will have to move the trip computer, just push up and pull out) free the vent assembly from the dash. Use finger clip to remove electrical connector. move the clips back to free the clock from the vent. separate the two halves of the clock by moving the clips back. remove bulb using small screwdriver and replace. reverse to reassemble

 

Thanks for this. Mine is burned out and I need to repalce it.
