Dodge Challenger Headlight Bulb Size

Additional Notes

• The 9012 is a single-filament enhanced halogen bulb operating at 12V and 55W with a PX22d base, and it serves as both the high beam and low beam bulb in the Dodge Challenger across the 2015-2023 model years when equipped with halogen headlights. Its use in both positions is possible because the housing optics, rather than a second filament, control beam direction.
• The 9008 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. The Dodge Challenger used this bulb for both high and low beam positions in the 2011-2014 model years under halogen capsule headlamp configurations, with the 2009-2010 high beam position also using it.
• The D3S is a mercury-free HID xenon discharge bulb with a PK32d-5 base and an integral ignitor, rated at 42V and 35W, and it is designed exclusively for projector-type housings. It appears in the Challenger's high and low beam positions from 2015-2023 on HID-equipped trims. Because it contains an integral ignitor, it is not interchangeable with D3R or other D-series bulbs that require a separate ignitor.
• The D1S is an HID xenon discharge bulb with a PK32d-2 base and an integral ignitor, rated at 85V and 35W, also restricted to projector-type housings. It is distinct from the D3S in both base type and operating voltage, making the two types mutually incompatible despite sharing a similar wattage rating. The Challenger used D1S bulbs in low beam positions from 2008-2014, and in high beam positions from 2011-2014.
• The 2009-2010 Challenger with HID headlamps used the 9005 halogen bulb for the high beam position rather than an HID type, while the low beam used D1S HID bulbs. This split configuration means the two beam positions in those years draw from entirely different bulb technologies and cannot be substituted for one another.
• The H4651, H4652, and H4656 are all 4x6-inch rectangular sealed beam units operating at 12V under the ANSI standard. Because sealed beam units integrate the filament, reflector, and lens into a single assembly, the entire unit is replaced rather than an internal bulb. The 1983 Challenger used H4651 for high beam and H4656 for low beam, while the 1978-1982 models used H4651 for high beam and H4652 for low beam.
• The H5001 and H5006 are sealed beam units used in the 1970-1974 Challenger. The H5001 is a 4-inch square unit used for high beam, while the H5006 is a 5.75-inch round unit used for low beam. Both operate at 12V and follow the ANSI sealed beam standard, meaning neither accepts a replaceable internal bulb.
• The 9012 and 9005 are both single-filament halogen bulbs operating at 12V, but they differ in wattage and base type. The 9005 uses a P20d base at 65W, while the 9012 uses a PX22d base at 55W. These differences in base configuration mean the two types are not physically interchangeable, even though both appear in Challenger high beam positions across different model years.
