OK, Revisiting my headlight issue. Had the headlights on. Turned them
off for a few, then turned them back on but they would not come on. I
have the SA lamps - and all four lamps failed to come on. I am at a
disadvantage because I moved and my Bentley has been misplaced. Is it
likely that all four of those lights would be out at the same time - not
burned bulbs, but some other reason?

Any tips on checking it out. Already checked the fuses. They are ok.

Thanks,

John
