Out last night and my headlights Kept going out and then back on.
They would go out for a 2 to 3 seconds and then come back on but the strange thing is its only the headlights. Tail lights, Rear sidemarkers, (Not sure about front markers) and the instrument lights stayed on.
Anyone got any ideas where to start looking for the problem?
 

had the same problem in my cherokee, ended up being my headlight knob was bad an had my lights flashing when i hit bumps on the highway or when i was up to speed, i tested it by going to a parking lot with a speed bump and driving over it several times
 
If you have upgraded your lights, the factory switch/wiring don't seem to like it. Could be the highbeam switch too.
 
Years ago I added 190/100W H4's to "Easy Bake" my black panel van, and immediately had this issue, I added a relay for each side and it cleared right up, later I altered the wiring as in those years of vans, Ford used 18 gauge wiring for the headlights, I upgraded from relay to connectors with 12 gauge and it's been bulletproof for over a decade.
