Headlights lost while driving

I'm driving down the road and all of a sudden my headlights and parking lights go out. I switch on the brights and they work but the main beams don't. Turn signals work, high beams work, brake lights and reverse lights work. Checked the fuses and nothing is blown. Does it sound like a relay, the light switch or wiring?

Thanks

Light Switch is toasted to me. You should go extra relays when new switch is installed.

Cheers,

For future reference it was the switch. Installed a new one and everything works as it should. As a side note, all the dash lights are much brighter with the new switch, it must have been on way its out for a while because I had noticed that the dash lights looked really dim before.

The switch usually goes bad because of the plastic pieces that hold the contacts in place inside the switch, to keep these from melting wire up the switch to use only as a signal to a relay here is a wring diagram I made up. (using higher wattage bulbs also exacerbates the problem.

Similar thing happened to me. Past owner added aux hellas but routed them through the switch not directly to the battery. I was driving in the deepest pitch black woods with brights on when suddenly everything fails and goes black. Luckily low beams still worked. All that power going through the switch would over heat the switch enough to cause the contact to bend and loose contact. Parts of the plastics were melted. The switch is not made for this. Use relays!
