Hyundai Sonata Headlight Bulb Size

Hyundai Sonata headlight bulbs utilize 3 distinct sizes across high and low beam configurations, including 9005, D3S, and H1 for high beams alongside 9005, D3S, and H11B for low beams. The replacement chart covers vehicle production years spanning 1989 through 2019 with corresponding bulb size specifications.

Additional Notes

The 9004 bulb, used in the Hyundai Sonata for both high and low beam positions from 1989-1994, is a dual-filament halogen type operating at 12V with separate wattage ratings of 65W for high beam and 45W for low beam. Its P29t base allows a single bulb to serve both functions within one housing.
From 1995 onward, the Sonata transitioned away from dual-filament bulbs, with dedicated single-filament bulbs assigned separately to high and low beam positions. This means the two beam functions require two distinct bulb types rather than one shared unit.
The H11B bulb, specified for the low beam position in the 2009-2010 Sonata, carries an asymmetric PGJY19-2 base. This asymmetric base design is not interchangeable with the standard H11 bulb, which uses a different base orientation, making substitution between the two types physically incompatible.
The D3S bulb, listed for the 2016-2018 Sonata with HID headlamps, is a mercury-free xenon discharge type rated at 42V and 35W. It incorporates an integral ignitor and is designed exclusively for projector-type housings, distinguishing it from the halogen alternatives listed for the same model years.
For the 2016-2018 Sonata, two separate bulb types are listed per beam position depending on headlamp configuration. Vehicles equipped with HID headlamps use the D3S, while those with halogen capsule headlamps use the 9005, making headlamp system type a necessary factor in determining the correct bulb.
The 9005 and 9006 bulbs share the same 12V operating voltage but differ in wattage and base type. The 9005 operates at 65W with a P20d base and is used for high beam, while the 9006 operates at 55W with a P22d base and is used for low beam. Despite their similar appearance, the two are not interchangeable.
The H1 and H7 bulbs both operate at 12V and 55W and follow the ECE standard, but they use different bases. The H1 uses a P14.5s base, while the H7 uses a PX26d base. Both types are approved in the US and Japan in addition to their primary ECE markets.
The 2019 Sonata is specified with the 9005 bulb for both high and low beam positions, making it the only model year in the specifications where a single bulb type covers both beam functions through separate, dedicated single-filament installations.
