Hyundai Elantra Headlight Bulb Size

Additional Notes

• The 9005 bulb is the most widely used type across the Hyundai Elantra headlight specifications, appearing in both high beam and low beam positions for the 2019-2023 model years, as well as in select 2014-2018 configurations. It is an ANSI-standard single-filament halogen bulb rated at 12V and 65W with a P20d base.
• The H7 bulb appears across multiple years in both beam positions, including high beam fitments for 2014-2018 and low beam fitments for 2001-2003 and a portion of 2019. It operates at 12V and 55W with a PX26d base and carries both ECE and US approval.
• The 2017 and 2018 Elantra each list three distinct low beam bulb types: D1S for HID headlamps, D5S for 25W HID headlamps, and 9005 for halogen capsule headlamps. This means the correct low beam bulb for those years depends entirely on which headlamp system is installed on the specific vehicle.
• The D5S is a low-voltage compact HID type rated at 12V and 25W, which distinguishes it from the standard D1S that operates at 85V and 35W. Both use different bases, PK32d-7 for the D5S and PK32d-2 for the D1S, making them physically incompatible with each other.
• The 9004 bulb, used in the Hyundai Elantra from 1992-1995, is a dual-filament ANSI halogen type rated at 12V with separate wattages of 65W for high beam and 45W for low beam. A single 9004 bulb serves both beam functions within one housing.
• The 9003 bulb, listed for 1999 and the early production period of 2000, is also a dual-filament halogen type but rated at 60W for high beam and 55W for low beam. It uses a P43t base, which differs from the P29t base of the 9004, and the two are not interchangeable despite both serving dual-beam functions.
• The 2000 Elantra carries a mid-year production change dated 7/1/2000, after which both the high beam and low beam specifications shift from the dual-filament 9003 to separate single-filament bulbs, H1 for high beam and H7 for low beam. This means two vehicles of the same model year may require entirely different bulbs depending on their production date.
• The H11B, used in the 2007 and 2008 Elantra low beam position, features an asymmetric PGJY19-2 base that physically prevents it from being installed in a standard H11 socket. Although both bulbs share the same 12V, 55W rating, the H11B is not a drop-in replacement for the H11 and the reverse is equally true.
• The 2014-2016 Elantra low beam position lists two different bulbs depending on headlamp type: 9005 for projector-type headlamps and H11 for non-projector headlamps. These two bulbs use different bases and wattages, with the 9005 rated at 65W and the H11 at 55W, so headlamp housing type is a required factor before selecting a replacement.
• The D1S HID bulb, listed for the 2017 and 2018 Elantra in both high and low beam positions with HID headlamps, includes an integral ignitor as part of its construction and is designed exclusively for projector-type housings. Its 85V operating voltage is generated internally by the vehicle's ballast and is not comparable to the 12V supply used by all halogen types in these specifications.
