Chrysler 300 Headlight Bulb Size

Additional Notes

• The Chrysler 300 uses two distinct halogen bulb sizes across its model years for high and low beam headlights. The 9005 bulb, a single-filament halogen unit with a P20d base rated at 12V and 65W, is specified for 2016-2023 models. The 9012, a single-filament enhanced halogen bulb with a PX22d base rated at 12V and 55W, is specified for 2011-2015 models. Although both are halogen types, they use different bases and wattage ratings, making them non-interchangeable.
• The D3S is an HID (xenon) discharge bulb specified as an alternative fitment across 2011-2023 model years, covering both high and low beam positions. It operates at 42V and 35W through a PK32d-5 base with an integral ignitor, and it is designed exclusively for projector-type housings. Its ECE-standard rating reflects worldwide certification rather than the ANSI standard used by the halogen options.
• For the Chrysler 300, the 9005 and D3S bulbs serve the same high and low beam positions in the same model years but are tied to different headlight system types. The 9005 applies to halogen headlight configurations, while the D3S applies to HID headlight configurations. Selecting the wrong bulb type for the installed headlight system would result in an incompatible fitment.
• The 9012 bulb used in 2011-2015 Chrysler 300 halogen configurations draws 55W, compared to the 65W draw of the 9005 used in 2016-2023 configurations. Despite both being single-filament halogen bulbs operating at 12V, their base types differ, with the 9012 using a PX22d base and the 9005 using a P20d base, which prevents cross-year substitution.
• The 1957-1971 Chrysler 300 high beam position uses the H5001, a 4-inch square sealed beam unit rated at 12V under the ANSI standard. The low beam position for the same years uses the H5006, a 5.75-inch round sealed beam unit also rated at 12V. Both are sealed beam units, meaning the entire assembly is replaced rather than an individual bulb.
• The 1956 Chrysler 300 specifies the H6024 for both high and low beam positions. The H6024 is a 7-inch round sealed beam unit rated at 12V under the ANSI standard. Like all sealed beam types in these specifications, the full unit is replaced when the light fails.
• The 1955 Chrysler 300 specifies the H6006 for both high and low beam positions. The H6006 is a 5x7-inch rectangular sealed beam unit rated at 12V. It is the only rectangular sealed beam format present in these specifications and is not interchangeable with the round or square sealed beam units used in other model years.
• Across the sealed beam years covered in these specifications, three different unit formats appear: the 4-inch square H5001 for high beams from 1957-1971, the 5.75-inch round H5006 for low beams from 1957-1971, the 7-inch round H6024 for both positions in 1956, and the 5x7-inch rectangular H6006 for both positions in 1955. None of these sealed beam formats are physically compatible with one another.
