Hyundai Genesis Headlight Bulb Size

Additional Notes

• The D1S is a high-intensity discharge (HID) xenon bulb rated at 85V and 35W, fitted with a PK32d-2 base that incorporates an integral ignitor. Its design is specific to projector-type housings, and it carries ECE certification for use across Europe and worldwide markets. In the Hyundai Genesis, the D1S serves as the low beam bulb across the 2009-2016 model years when the vehicle is equipped with HID headlamps.
• The H11 is a single-filament halogen bulb rated at 12V and 55W, using a PGJ19-2 base. It holds ECE certification and is also approved for use in the United States. It functions as the low beam bulb on Hyundai Genesis models fitted with halogen capsule headlamps across the 2009-2015 model years.
• The H11B shares the same 12V, 55W rating as the H11 but uses an asymmetric PGJY19-2 base, which physically prevents it from being installed in a socket designed for the standard H11. Despite their similar names and electrical ratings, H11 and H11B bulbs are not interchangeable due to this base difference.
• The H7 is a single-filament halogen bulb rated at 12V and 55W with a PX26d base, carrying ECE certification and additional approval in the United States and Japan. It is listed as the high beam bulb for the Hyundai Genesis across the 2009-2013 model years, as well as the 2014 model year in certain configurations.
• The 9005 is a single-filament halogen bulb rated at 12V and 65W, built to the ANSI standard used in the United States and Canada. At 65W, it operates at a higher wattage than the ECE halogen types listed in these specifications. It is listed for the 2015 Genesis high beam position with halogen capsule headlamps and the 2016 low beam position.
• The 2014 Hyundai Genesis introduced a production date split, with the H11B replacing earlier bulb types in both the high and low beam positions for vehicles built from February 12, 2014 onward. This means two different bulb fitments exist within the same model year depending on the vehicle's build date.
• The 2015 and 2016 Hyundai Genesis carried two distinct headlamp systems simultaneously, with HID-equipped vehicles using the D1S and halogen-equipped vehicles using different bulb types for both high and low beam positions. Substituting a bulb from one system into the other is not supported by these specifications.
• Across the full model range covered by these specifications, the low beam position shows greater variation in bulb type than the high beam position, with the D1S, H11, H11B, and 9005 all appearing depending on the model year and headlamp system fitted.
