Just bought 84 cj7, Can't wait to join the jeep family. I don't know what I should be looking for as far as the headlights go, It appears as I turn a knob, and then the lights are on, turn again and the lights are off. My question is, did the 1984 cj7 come with high and low beam? or is on and off all you get?
The dimmer switch is in the floor board on far left side.

If I'm correct there a fusible link for the headlights.
Probably of the starter solonoid.

The problem is the headlight switch itself - it's one of the most common failures on these cars. The part, brand-new, is about $158 from ECSTuning.com. Replacing it involves removing the airbag and steering wheel - not difficult but a little nerve-wracking due to the power of the airbag.
If this is something you want to tackle on your own, reply back here and I can give you a step-by-step on doing the work yourself. Or you can go to a shop/dealer and just have them do it. They'll probably charge you at least two hours' labor, even though it's a 40 minute job. Let me know what you would like to do.

Check the Headlight Switch. If your headlights come on automatically check the headlight sensor and its associated relay.

Most scrapyards will sell the connector if they aren't going to save the harness. You can remove the wires by using a thin piece of metal pushed in from the switch side of each wire to bend down the lock tab. Draw a diagram of where the wires go before changing it.

check the bulbs again then go from there not uncommon for bulbs to blow at the same time
