Nissan LEAF Headlight Bulb Size

Additional Notes

• The 9005 bulb follows the ANSI standard used in the US and Canada. It is a single-filament halogen type with a P20d base, rated at 12V and 65W. On the Nissan LEAF, it serves as the high beam bulb for the 2011-2012, 2019-2020, 2022-2023 model years and as the low beam bulb for the 2011-2012 model years.
• The 9008 is an ANSI-standard dual-filament halogen bulb with a P26t base, rated at 12V with a dual wattage of 65W for high beam and 55W for low beam. Its dual-filament design means a single bulb handles both high and low beam functions, which is reflected in its fitment across both beam positions on the LEAF for the 2013-2018 model years with halogen capsule headlamps.
• The H9 follows the ECE standard used in Europe and worldwide, though it carries US approval as well. It is a single-filament halogen bulb with a PGJ19-5 base, rated at 12V and 65W. On the LEAF, it appears as a high beam option for the 2011-2012 model years without a headlamp type qualifier, and for the 2013-2018 model years specifically with LED headlamps.
• The H11 is an ECE-standard single-filament halogen bulb with a PGJ19-2 base, rated at 12V and 55W. It is the designated low beam bulb for the Nissan LEAF for the 2018-2020 and 2022-2023 model years under halogen capsule headlamp configurations, as well as the 2022-2023 entries without a headlamp type qualifier.
• The 9005 and 9008 share the same high beam wattage of 65W but use different base types, P20d and P26t respectively, making them physically incompatible with each other despite the identical wattage rating.
• The H9 and H11 both follow the ECE standard and carry US approval, but they use different bases, PGJ19-5 and PGJ19-2 respectively, and operate at different wattages, 65W and 55W. These differences make them non-interchangeable despite their shared standard and approval status.
• For the 2018 model year with halogen capsule headlamps, the Nissan LEAF lists both the 9008 and the 9005 as high beam options, and both the 9008 and H11 as low beam options, indicating that fitment varies depending on the specific headlamp assembly installed on the vehicle.
• The 9008 dual-filament bulb, used across both beam positions in the 2013-2017 halogen capsule headlamp configurations, operates on a single base with two filaments switching between 65W for high beam and 55W for low beam. This differs from systems using separate bulbs for each function.
• The presence of both ANSI-standard and ECE-standard bulbs across different LEAF configurations reflects the use of different headlamp assemblies over the model's production span, with the headlamp type qualifier in the specifications serving as the critical factor in determining the correct bulb for a given vehicle.
• For the 2011-2012 model years, the high beam position lists both the 9005 and H9 without a headlamp type qualifier, indicating that both bulb types were used depending on the specific headlamp assembly, and the two are not interchangeable due to their differing base types.
