flashing headlights

[groovingal42]

ok.. So our 1973 GMC Sprint likes to flash its headlights on/off constantly once the lights have had time to warm up. We have changed bulbs, connectors, switches you name it. Is there something we are missing? We can't go cruisin @ night!!

so we searched and read farther and did some more grounding hopefully that will work next time I will search further thanks for the help read thru flickering headlights.
