A headlight should not go out due to trailer wiring being installed; the only reason this might happen is if there is somehow a short on the circuit for the running lights, which is connected to the headlights. You may also simply have blown a fuse for one reason or another so check the owner's manual for your vehicle and see if you have a blown fuse that simply needs to be replaced.

I have added links to a couple help articles on wiring which I strongly recommend taking a look at.
