'84 F-150 Blown Fuse? Headlights not working...

My 1984 Ford F-150's headlights went out this morning. Pretty sure it's a blown fuse...no idea where the box is. Looked at some diagrams, can't figure it out. Anyone know? How about which fuse is the right one for headlights? Help is greatly appreciated!!! ))

The headlights are not fused. The only thing they have is a fusible link over at the pass fender under the hood.

The best thing to do is get a testlight or voltmeter, turn the headlights on, and probe the dimmer switch in the floor. If you have voltage on one of the wires at the dimmer, then the headlight switch is ok, and it might be the dimmer switch if you do not have voltage on any of the other two wires.

If you do not have any voltage on any of the wires at the dimmer switch, I would pull the dash and check the headlight switch itself.

A funny thing happened to me once. I had a headlight go out in my truck, so I replaced it. Two days later, when I went to leave a friends (at 11pm), both of my headlights went out when I turned them on. After searching high and low for three days, I found the problem. Both headlights blew out at the same time. It was time for the old one to go out, and the new one was defective. I replaced them and have had no issues since. From now on I will always replace the headlights in pairs.

The Headlamp switch is on a circut breaker. This will cause the lights to Flicker or flash on and off, but wont let the lamps go completely out when there is a short circut or defective headlamp switch.

The dimmer switch would be the first thing I would check as well. Wet feet and corrosion are very common cause of dimmer switch failure.
