Originally internally coded as LFA, the 2015 Sonata was unveiled in Korea late March 2014, and was unveiled in America at the 2014 New York International Auto Show.
Did you check if voltage is being applied to the appropriate bulb connection when the headlamp is turned on?
If so, check that there's a good earth connection to the bulb.
If you don't have a DMM (digital multimeter) to check for voltage or an earth, run a temporary cable between an earth point (-ve pole of battery) and the earth connection on the bulb and check. At least this will eliminate the possibility of a faulty earth connection
