Hyundai Santa Fe Headlight Bulb Size

Additional Notes

• The 9003 bulb, used in the Hyundai Santa Fe across the 2001-2006 model years for both high and low beam functions, is a dual-filament halogen type operating at 12V with a 60W/55W rating and a P43t base. Its dual-filament design allows a single bulb to serve both beam functions within the same housing.
• The H7 bulb appears across multiple model years in both high and low beam positions. It is a single-filament halogen bulb rated at 12V and 55W with a PX26d base, built to ECE standards but also approved for use in the US and Japan.
• The H11B bulb is used exclusively in the low beam position on the Santa Fe from 2010 onward through several model years. It is a single-filament halogen bulb rated at 12V and 55W, distinguished by an asymmetric PGJY19-2 base. That asymmetric base design makes H11B physically incompatible with standard H11 sockets, despite the two types sharing similar electrical ratings.
• The D1S and D3S bulbs are HID (xenon) discharge types, both rated at 35W but operating at significantly different voltages: 85V for D1S and 42V for D3S. Both include an integral ignitor and are designed for projector-type housings. These two types are not interchangeable with each other or with any halogen bulb in the specifications.
• The D3S is a mercury-free formulation, distinguishing it from the D1S, which does not carry that designation in the specifications.
• The 9005 bulb, used in the 2019-2022 Santa Fe for both high and low beam positions, is a single-filament halogen type rated at 12V and 65W with a P20d base. At 65W, it operates at a higher wattage than the H7 and H11B halogen types also present in the specifications.
• The 2017 and 2018 Santa Fe high beam positions list two distinct bulb sizes per year: D1S for vehicles equipped with HID headlamps and H7 for those with halogen capsule headlamps. This reflects a trim-level or factory option split rather than a mid-year production change.
• The 2009 Santa Fe low beam position carries two separate entries distinguished by production timing: H7 for the early model and H11B for the late model. A vehicle from that year requires production date verification before a replacement bulb size can be determined.
• The 2013-2016 Santa Fe low beam position lists both H11B and D3S as valid sizes depending on headlamp type, while the high beam for those same years lists only H7. This means HID-equipped vehicles in that range used different bulb families for low and high beam functions simultaneously.
• The D1S and D3S types use PK32d-2 and PK32d-5 bases respectively. Although both share the PK32d base family designation, the differing suffix numbers indicate physically distinct pin configurations, and the two bulbs are not cross-compatible.
