Hyundai Elantra GT headlight bulbs utilize 9005 and H7 sizes for high beam applications, with H7 and H11 sizes for low beam functions. The replacement chart covers 2013 to 2020 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9005 bulb, specified for the high beam position in the 2019-2020 Hyundai Elantra GT with halogen capsule headlamps, is a single-filament bulb operating at 65 watts with a P20d base. It is not interchangeable with H7 bulbs due to differences in base design and wattage.
The H7 bulb appears across multiple positions in the Elantra GT specifications. It serves as the high beam bulb for the 2013-2018 model years and as the low beam bulb for the 2019-2020 model years with halogen capsule headlamps. H7 is a single-filament bulb rated at 55 watts with a PX26d base.
The H11 bulb is specified for the low beam position across the 2013-2018 model years. It is a single-filament bulb rated at 55 watts with a PGJ19-2 base. Despite sharing a similar wattage with H7, the two bulb types use physically different bases and are not interchangeable.
For the 2019-2020 model years, the high beam and low beam positions use different bulb types, 9005 and H7 respectively, meaning the two positions do not share a common bulb even within the same vehicle year.
For the 2013-2017 model years, the high beam and low beam positions use H7 and H11 respectively. Although both are 55-watt halogen bulbs, their base configurations differ, and substituting one for the other is not supported by the specifications.
The 2018 model year represents a transitional point in the specifications. The high beam shifts from H7 to a configuration that retains H7, while the low beam changes from H11 to H11 under the halogen capsule headlamp designation, maintaining the same bulb types as prior years but adding the halogen capsule qualifier.
The halogen capsule headlamp qualifier present in the 2018-2020 entries indicates that these fitments apply specifically to vehicles equipped with that headlamp assembly type, suggesting the Elantra GT offered more than one headlamp system configuration during those years.
The 9005 bulb type uses a snap-in retention tab rather than a twist-lock base, which is a key physical distinction from the bayonet-style PX26d base used by the H7 bulb specified for other positions and years in these specifications.
