Need Help! Headlights wont turn off.

[wcruzv]

...ok so today my factory alarm on my new sedan got activated when a friend got out of the car, this car didnt came w/ a remote, i just need to get the car on ACC or ON and it shuts off, but the thing is that after i shut down the alarm the headlights stayed on...i started the car, turned it off, basically did everything and the headlights wont turn off... since im a newbie idk if i need to hit a hidden button or w/e... i even had to disconnect the batt. cause if i didnt i was gonna end up with a dead batt.

i will really appreciate any help on this, thanks in advance!
