Do your inside gauge lights turn on?
I had an issue with my interior lights not working, it was the light switch itself. It wasn't sending a feed to the inside lights. The same thing could ha e happened for you, but its not sending to the headlights. Is try and check the wires, see if they have power. I spent weeks trying to figure it out, took it to a shop and be put direct power to the lights and it worked. Hope this helps man.
