Jeep Grand Cherokee Headlight Bulb Size

Additional Notes

• The 9005 bulb is the most frequently specified high beam type across the Jeep Grand Cherokee range, appearing in halogen-equipped models from 2005-2011 and as the standard halogen option in HID-era models from 2014-2017. It follows the ANSI standard used in the US and Canada, operates at 12V and 65W, and uses a P20d base with a single filament.
• The D3S bulb serves as the HID high beam and low beam option across the 2014-2021 model years. It is a mercury-free xenon discharge bulb operating at 42V and 35W, built to ECE standards, and requires a projector-type housing along with an integral ignitor housed within the bulb itself.
• The 9004 bulb, specified for the Jeep Grand Cherokee from 1993-1998, is a dual-filament halogen type with a P29t base rated at 12V and 65W for high beam and 45W for low beam. Its dual-filament design means a single bulb serves both beam functions, distinguishing it from all other bulb types listed in these specifications.
• The 9005XS and 9006XS variants, used in 1999, 2003, and 2004 model years, are straight 180-degree base versions of the standard 9005 and 9006 bulbs respectively. Despite the physical base difference, their electrical ratings remain identical to their non-XS counterparts, and the XS designation signals a fitment distinction rather than a performance one.
• From 2014-2020, the Grand Cherokee high beam position required either a D3S or a 9005/H9 depending on headlamp type, meaning HID-equipped and halogen-equipped vehicles of the same model year take entirely different and non-interchangeable bulbs in the same position.
• The low beam position shifted from the dual-filament 9004 (1993-1998) to the single-filament 9006/9006XS (1999-2010), then to H11 or D1S from 2011 onward. The H11 and 9006 share the same 12V, 55W rating but use different base types, PGJ19-2 and P22d respectively, making them physically incompatible despite identical wattage.
• The D1S, used in low beam HID applications for 2008-2011 model years, operates at 85V and 35W, which is a notably higher ignition voltage than the D3S at 42V. Both are projector-housing HID types with integral ignitors, but their PK32d-2 and PK32d-5 bases are distinct and the two types are not interchangeable.
• The H9 high beam bulb, specified for 2019-2021 halogen-equipped models, operates at 12V and 65W with a PGJ19-5 base. The 9005, which filled the same high beam role in earlier halogen models, shares the same wattage but uses a P20d base, making the two physically incompatible despite equivalent power output.
