Last night i went to turn on my headlights so i could cruise at night, when i flipped the switch the head lights refused to turn on, so i turned them off and back on (happened that morning, turning them off and back on helped) but nothing happened, i then tried it again still nothing. I decided to turn the car off and turn it over again, just to eliminate everything still nothing, I then pulled out the fuses to my headlights but there all fine, i looked at the module and it seams to be fine too. i can't figure out why they wont turn on.

Your Corolla has daytime running lights (DRLs). A photocell determines whether it is day or night. Your DRLs turn on automatically in daytime without you operating the light control ("headlight") switch. Your DRLs are actually your headlights on low beam. At night, the photocell senses it is dark and disables the DRLs. When you set the light control ("headlight") switch to HEAD, the head relay closes and the headlights should turn on. Since they don't, I suggest opening the engine room junction block and checking the 40A MAIN fuse and the 10A LEFT HEAD (UPPER) and RIGHT HEAD (UPPER) fuses. In engine room relay block 5, check the 10A LH-LWR HEAD and RH-LWR HEAD fuses. Replace any blown fuses and the headlights should be working normally again
Right now, I'm thinking the head lamp switch assembly has a problem? See the wire color in the top of head lamp, that is voltage, fuse protected, hot all the time. When problem is ongoing, you could use a test lite, check for voltage at fuse circuit?
The headlamp switch assembly is located on headlamp ground circuit. There could be a wiring problem, somewhere. I can only help with testing.
Certainly is an unusual symptom. You might try unplugging the headlight switch and replacing it with one from an auto salvage yard. The flashers also might be part of the problem. There are relays under the hood and on the fuse panel but I am guessing you've looked at these already.
There is a relay that controls the headlights, volvo calls it a step relay. You will have to check that power is getting to this relay. If not, check all fuses and wiring. If power supply checks out ok, you may have to replace the relay. Let me know if you need any more info or a wiring diagram.
Im not sure I am following you. When it gets dark enough the "daytime" running lights should go off and the headlights and tail lights should come on for night time driving. The head light switch must be set in the "auto" position.
