Only one side wont work, but when in parking position they light up only the head light wont work on the one side, and not bulb??
My Kia rondo's left head lights wont work, checked bulb and fuses they ok on 2008 Kia Rondo
If the bulbs are ok and fuses for sure. Then you need to check for power at the socket where the bulb plugs in. If you have power, check the contacts and repair as needed. If not, you need to trace the wire back towards the fuses and find where the wire is broken and repair as needed.
