Hyundai Santa Fe Sport Headlight Bulb Size

Additional Notes

• The D3S bulb is the most frequently specified type across the Hyundai Santa Fe Sport headlight data, appearing in both high beam and low beam positions across all listed model years (2013-2018) whenever HID headlamps are fitted.
• D3S is a high-intensity discharge bulb that operates without an external ignition module, as the igniter is built directly into the bulb base. This design makes it non-interchangeable with other D-series HID types such as D1S or D2S, which use separate ballast and igniter configurations.
• The high beam position on the 2013-2015 Santa Fe Sport with HID headlamps and the low beam position on the same years with HID headlamps both call for D3S, indicating that some trim configurations used HID technology across both beam functions simultaneously.
• For the 2017-2018 model years, the high beam specification shifted from H7 (used in 2013-2016 halogen configurations) to 9005, representing a change in the halogen bulb standard for that position between those production periods.
• The H11B specified for low beam halogen configurations in the 2013-2016 Santa Fe Sport is a variant of the H11 family but features a notched base that prevents standard H11 bulbs from seating correctly. Substituting a regular H11 in an H11B socket is not supported by the specifications.
• The 9005 bulb, used in high beam halogen applications for 2017-2018 and also listed as the low beam size for those same years in non-HID configurations, is a single-filament halogen type rated at a higher wattage than H7, which affects heat output and socket compatibility.
• H7, specified for high beam halogen applications in the 2013-2016 Santa Fe Sport, is a single-filament bulb with a two-pin base. It is not physically or electrically interchangeable with 9005, which uses a different locking tab base design.
• The Santa Fe Sport headlight specifications consistently present two distinct fitment paths per model year: one for vehicles equipped with HID headlamps and one for vehicles equipped with halogen capsule headlamps. Bulb selection depends entirely on which headlamp system the vehicle was built with.
• Installing a D3S bulb without the corresponding OEM HID ballast and wiring harness is outside the scope of these specifications, as D3S operates on high-voltage AC power supplied by the ballast rather than standard 12V DC vehicle power.
• The low beam halogen specification for the 2013-2016 Santa Fe Sport (H11B) and the high beam halogen specification for the same years (H7) are two distinct bulb families with no cross-compatibility, despite both being single-filament halogen types used on the same vehicle.
