The 2017 Hyundai Sonata uses either D3S or 9005 bulbs for the headlights. Both sizes are listed for the low beam and high beam, so confirm whether your Sonata has the HID or halogen headlight configuration before ordering. D3S applications are associated with HID headlights, while 9005 applications are the alternate listed headlight fitment.
Rear lighting also varies with the headlight setup. Models with halogen headlights use 2357R bulbs for the brake and tail lights and 2357A bulbs for the rear side markers. Models with HID headlights use integrated LED brake, tail, and rear side-marker lighting instead. The front turn signal uses 2357A, and the rear turn signal uses 1156A.
