COOLBLUES... & CHAD both have it pretty right.
You didn't tell us what kind of vehicle, or if the lights all worked when the light switch is off. It makes a difference.
If you have brake lights, turn signal lights etc. when the headlights are off, then they go out when you turn the headlights on, you have a ground problem in the rear of the vehicle.
Some vehicles ground ALL of the lights in the rear with only one wire, and if the connection is compromised, there is no way for them to work.
With the headlights off, there is a ground path back through the headlamps to ground. When the headlamps are on, the potential goes away, as the "ground" that was working now has power to it.
Check this out.
Good Luck

You have blown fuses or a plug came unpluges in your trunk. Chech your wires in the trunk and look for anything unplugged going to your tail lights.. You didn't say that all of those worked eith the lights off either.. If they do then your head light switch wires Are shorting out everything to the rear. The other possibility is there could be a short in 1 or more fuse boxes
You never said the make of the car.

you have blown fuses or a plug got here unpluges on your trunk. Chech your wires interior the trunk and seem for something unplugged occurring your tail lights fixtures.. You did not say that one and all of those worked eith the lights fixtures off the two.. in the event that they do then your head gentle change wires Are shorting out each and everything to the rear. the different threat is there's a quick in a million or extra fuse packing packing containers You by no potential suggested the make of the vehicle.

Your headlight switch is defective. Although I don't know why your brake lights are not working.
The brake lights are normally a completely different circuit.
It would help to know what kind of car you have.

Don't laugh at this. It may work. My son stored his change in the ashtray of his car. Change shorted out the lighter and other lights. When he removed the coins, he regained all of his lights, signal etc.

Sure sounds their is a bad ground that will cause this problem.
Do the lights work when the headlights are off?

look close at your bulbs you may have to try replacing them one at a time start with rear brake lights

replace the fuse ... headlights are on a circuit breaker in the switch itself, the rest are fused at the fuse panel
