I HAVE AN 92 AUDI 100S LAST NIGHT WHEN I GOT IN TO MY CAR NONE OF MY LIGHTS WERE WORKING ONLY THE DASHBOARD LIGHTS MY WINSHIELD WIPERS, HEAD LIGHTS, BLINKERS WERE NOT WORKING THE ONLY WAY MY HEAD LIGHTS WOULD WORK IS IF I HELD THE SWITCH IN LIKE HOW YOU FLASH PEOPLE I CHECKED ALL MY FUSES I THINK ITS AN ELECTRICAL PROBLEM I RELLY HOPE ITS NOT THO LOL IF ANY ONE HAS AN IDEA WHAT IT COULD BE JUST COMMENT ME BACK THANK YOU

You said that it did not have any lights but you did not mention if it started or not, If it started then I would ask did you try to turn the key back just a little bit where as it could be your ignition switch..getting old or If it did not start you could be up against a relay that is not switching correctly...or it has a corroded connection pull each of the relays and reseat them so they have a good connection...Turbo Rhatt

I think its the ignition switch. Need to replace it. research it.
