Nissan Versa Headlight Bulb Size

Additional Notes

• The 9003 bulb is the most widely represented type across the Nissan Versa headlight specifications, appearing in both high beam and low beam positions for the 2013-2020 model years. It follows the ANSI standard used in the US and Canada, operates on a 12V circuit, and uses a dual-filament design rated at 60W for high beam and 55W for low beam, both housed in a single P43t base.
• Because the 9003 bulb carries dual filaments, a single unit serves both the high beam and low beam functions simultaneously. This contrasts with single-filament bulbs, which are dedicated to one beam position only.
• The 2021 Nissan Versa is listed with two separate bulb fitments for both the high beam and low beam positions: the 9003 and, alternatively, the H9 or H11. This indicates that two distinct headlight configurations were available for that model year.
• The 2020 Versa specifies the 9003 bulb with the qualifier "With Halogen Capsule Headlamps," indicating that this fitment applies only to vehicles equipped with that specific headlamp type.
• For the 2022-2023 model years, the high beam position uses the H9 bulb. The H9 is a single-filament halogen bulb rated at 12V and 65W, built to the ECE standard and approved for use in the US. It uses a PGJ19-5 base.
• The H9 operates at 65W, which is higher than the 60W high beam output of the dual-filament 9003. Despite both being 12V halogen bulbs, they are not interchangeable due to differing base types: the H9 uses a PGJ19-5 base, while the 9003 uses a P43t base.
• For the 2022-2023 model years, the low beam position uses the H11 bulb. The H11 is a single-filament halogen bulb rated at 12V and 55W, built to the ECE standard and approved for use in the US. It uses a PGJ19-2 base.
• The H11 and H9 share the same wattage rating of 55W and 65W respectively and are both ECE-standard single-filament bulbs, but their base types differ. The PGJ19-2 base of the H11 is not compatible with the PGJ19-5 socket of the H9, making them non-interchangeable despite their physical similarity.
• The transition from the dual-filament 9003 to separate single-filament H9 and H11 bulbs between the 2021 and 2022 model years reflects a shift from a shared-filament headlight system to a split-function system, where dedicated bulbs handle each beam position independently.
• All three bulb types listed in the specifications, the 9003, H9, and H11, operate on a 12V electrical system, which is standard across conventional passenger vehicle electrical architectures.
