You can fit LED bulbs to all of the Jaguar instruments, they are meant to last a lot longer than traditional bulbs.
In my MK2 when I fitted LED bulbs I cleaned inside where the bulbs sits, there are blue plastic shields inside. After cleaning the instruments have a pleasant blue tinge to them. I have owned old Jags for years and they all shone a dull yellow. I can only presume that they had a blue tinge when new. Anyone going to admit to being old enough to remember what they were like when new?
