For the 1999 Hyundai Sonata, the supplied fitment data does not list a low-beam or high-beam headlight bulb, so verify the headlamp assembly and vehicle configuration before ordering replacement headlight bulbs. No projector versus non-projector distinction is provided.
Fog lights use either H3 or H3C, indicating that the correct bulb depends on the fog-light assembly installed. Check the existing bulb and connector before purchasing.
