Running light fuse?

I was installing aftermarket LED headlights, turn signal bulbs, and running light bulbs. Upon taking out the old connector and installing the new one with the new bulb. The front and rear running lights on the left side went out. While the side that was not tampered with remained lit. I thought the aftermarket connector was making a bad connection so i replaced it with the same stock connector and stock bulb and still nothing. I finished the job with aftermarket housings, headlight and turn signal bulbs with resistors added to the turn signal circuit. I dont know whether i popped a fuse i still have to look. But i'm not sure that'll fix the problem.
