Sounds like the circuit breaker for the headlights. It might be overheating (worn out, bad connections or whatever) or you may have a short and its just tripping like its supposed to. Unlike the circuit breakers in a house, these reset themselves automatically for obvious reasons. I'v enever had an Imperial do what you describe but a 1950 Studebaker once did it to me all night. We finally found that the luggage in the trunk had pressed against a tail light wire causing a short and it made the breaker keeep tripping. Your Imperial shouldn't have any exposed wires there but there's plenty of places things in the lighting circuits can get shorted. ________________________________________________________________ GET INTERNET ACCESS FROM JUNO!
