Hi to all,

The headlights, both sides, don't work.  The flash lights don't either.  High or low beam.  It's an '85 camper.  
I checked;
fuses all good,
changed the switch with an other one and they are still not working.
the side markers work,

Checked the Bentley, but I could not find anything to go on there.  I don't even know what to look at now.  As much as I can understand by looking at the wiring, could not point to anything that would be at fault.

Anyone?  Would be much appreciated.
Zoltan
