Headlights stopped working....

Hey guys

Well the other night i went to drive my SC for the first time this yr and i drove to visit someone and then when i left it was dark so i went to turn on ym headlights and i only got my running lights. I have just installed a aftermarket Tach and i did wire that into the power wire for the lights but i am pretty sure after i did that that i checked to make sure the headlights still worked and they did. So my question is what is a good sequence to go through to try and find the prob? it frustrates me cause i am just getting my vac leaks fixed and now i have no headlights so i cant take the car out if i will be out past dark haha. Please any help will be greatly appreciated. thanks

your local auto parts sotre has them for about $15.

get power from somewhere else, it's already weak enough the way ford designed it.
