2009 accent headlights won't turn on
Just replaced headlight assembly and
when I got the new assembly in the
headlights won't come on just marker
take the bulbs from the other assemble and put it in the new to see if it works then.
or check the low beam fuse in under the hood .
Since you just messed with your lights I'd look over the connections carefully and check your fuses to see if you accidentally shorted something (if the lights were on at any time when you were changing out the lights). There is a (nearly) hidden relay for the headlights up under the dash and I have an article that shows you the type and location of that relay: http://www.shareyourrepair.com/2016/03/hyundai-accent-headlights- will-not-come-on.html
