My hazard's developed a strange defect whereby the system would function correctly, but when switched off, the warning light would remain on but quite dim. With the slightest tap on the side of the flasher unit, the light would extinguish. The unit fitted in the car [in the left of the photo] was I think probably the original. Anyway, I've replaced it with a modern electronic unit sourced from Car Builder Solutions with whom I have no affiliation and the system now functions as it should do.
Anyway, I though I would pass this on.
