Ram 1500 Headlight Bulb Size

Additional Notes

• The 9005 bulb is the most frequently specified high beam bulb across Ram 1500 model years in these specifications, appearing in both high beam and low beam positions depending on the year and headlamp configuration. It is an ANSI-standard single-filament halogen bulb rated at 12V and 65W with a P20d base.
• The H11 bulb is the most frequently specified low beam bulb across these specifications. It 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 PGJ19-2 base rated at 12V and 55W.
• The 9008 bulb is a dual-filament halogen bulb with a P26t base rated at 12V and 65W on the high beam filament and 55W on the low beam filament. In the Ram 1500 (2011-2012) with a 2-headlamp system, this single bulb serves both high and low beam functions within one housing.
• The 9012 bulb is an ANSI-standard single-filament enhanced halogen bulb with a PX22d base rated at 12V and 55W. It is specified for the low beam position in projector-type headlamp configurations for the 2013-2015 model years.
• The 9006 bulb is specified only for the 2021 high beam position. It shares the same ANSI standard and 12V rating as the 9005 but draws less power at 55W and uses a P22d base rather than the P20d base of the 9005, making the two bulbs physically incompatible despite their similar appearance.
• For the Ram 1500 (2011-2012), the headlamp count determines the bulb type entirely. The 2-headlamp system uses the dual-filament 9008 for both beams, while the 4-headlamp system uses the 9005 for high beam and H11 for low beam as separate dedicated bulbs.
• For model years 2016-2019, the low beam bulb type depends on whether the vehicle is equipped with projector-type headlamps. Projector configurations use the 9005, while non-projector configurations use the H11. These two bulbs have different base types and wattage ratings and are not interchangeable.
• The 9012 and 9005 bulbs are both used in low beam projector-type headlamp configurations across different model years, with 9012 specified for 2013-2015 and 9005 specified for 2016-2019. Despite both being ANSI-standard single-filament halogen bulbs at 12V and 55W, they use different bases, PX22d and P20d respectively, and are not interchangeable.
• The 2020 model year specifications carry the qualifier "With Halogen Capsule Headlamps" for both the high beam 9005 and low beam H11 entries, indicating that the bulb sizes listed apply specifically to that headlamp variant.
• The P20d, P22d, PGJ19-2, PX22d, and P26t base types referenced across these bulbs are each physically distinct. A bulb with one base type cannot be seated into a socket designed for another, making base type a critical factor in fitment.
