Hello,

It seems to me that there are four lighting computers on our xj6's.
One mounted on each side of the radiator and two in the trunk. After
checking for good earth I would look for output from the light switch
to these modules. Come to think of it, perhaps you should remove your
light switch assembly before checking your modules; there are several
diodes in the light switch that go bad and could cause inoperative
lights.

Another thing... does your alarm system operate?

Cheers,
Blake
