Dodge Viper Headlight Bulb Size

Additional Notes

• The D3S is a mercury-free HID (xenon) discharge bulb rated at 42V and 35W, built to the ECE standard and fitted with a PK32d-5 base that incorporates an integral ignitor. It is designed exclusively for projector-type housings. The Dodge Viper uses the D3S for both high and low beam positions in the 2015-2017 model years.
• The D1S is an HID (xenon) discharge bulb rated at 85V and 35W, also built to the ECE standard, but fitted with a PK32d-2 base rather than the PK32d-5 found on the D3S. Despite sharing the same wattage, the two HID types operate at different voltages and use different bases, making them non-interchangeable. The Viper uses the D1S for the low beam position in the 2005-2006 and 2008-2010 model years.
• The 9005 is an ANSI-standard single-filament halogen bulb rated at 12V and 65W, using a P20d base. It serves as the high beam bulb on the Dodge Viper from 1992-1995 and as the low beam bulb from 1992-2000.
• The 9005XS shares the same 12V, 65W rating as the 9005 but uses a straight 180-degree base configuration rather than the P20d base. This base difference means the 9005XS and 9005 are not directly interchangeable despite their otherwise similar electrical characteristics. The Viper uses the 9005XS for the high beam in the 2003-2006 and 2008-2010 model years.
• The 9011 is an ANSI-standard enhanced single-filament halogen bulb rated at 12V and 65W, using a PX20d base. The PX20d base differs from the P20d base of the 9005, which prevents cross-fitment between the two types. The Viper uses the 9011 for the high beam position in the 1996-2002 model years.
• The 9006 is an ANSI-standard single-filament halogen bulb rated at 12V and 55W with a P22d base, while the 9006XS carries the same voltage and wattage but uses a straight 180-degree base. The lower 55W rating distinguishes both 9006 variants from the 65W 9005-series bulbs used in the high beam position. The Viper uses the 9006 for the low beam in 2001-2002 and the 9006XS in 2003-2004.
• Across the Viper's headlight specifications, the low beam position transitions through four distinct bulb types across the full model range: the 9005, 9006, 9006XS, D1S, and D3S. Each of these types uses a different base configuration, and none are interchangeable with one another.
• The D3S and D1S bulbs both conform to the ECE standard, which is applied globally outside North America, while all halogen types listed for the Viper conform to the ANSI standard used in the United States and Canada. The two regulatory frameworks reflect different testing and classification systems rather than differences in physical output alone.
