Help!!

I own a 1992 Jeep Wrangler and I went to take off tonite and I turn the head lights on and they did not work at all. I do have tail lights and running lights, but no high or low beams headlights at all.. I do not have a owners manual for the Jeep. I just purchased the Jeep a couple of months ago. I never had it out in the night time before and I'm not sure if its just started not working or they never ever work when I got it.?? I tried to check the fuse box and to see if there is a spot for head lights, but cant tell if there is or not?? OR if there is another spot for a larger fuse for the headlights??? Can any one help me out on what to do??? Thanks

My guess would be some wiring has a short, or the headlamp switch is bad.
