Thread: 98 Defender headlights

What is that relay behind the instrument cluster?
Mine is yellow, not pink, but probably still does the same thing.

OK, found the fault.

It was in the combination indicator/high-beam switch.
The contact where power comes into the switch (Blue wire) has a brass post which is pressed into a contact strip at its base. The strip then has contact "blobs" at either end for switching over between low and high beam.

The joint between the post and the contact strip was loose, and with slight jiggling, the headlights would flicker into life, and extinguish when the jiggling stopped.
Solution was to put a nice blob of solder at the base of the post and spreading out onto the back of the contact strip.
Fingers crossed that it doesn't crack the solder - if it does, then it'll be time for a new combination switch (and another $180).

Thanks to all who helped with the diagnosis.
