Dodge Dakota headlight bulbs utilize 9008, 9007, and 9004 sizes for both high beam and low beam applications, with bulb specifications varying across production years. The replacement chart covers 1987 through 2010 model years and details the corresponding bulb sizes for each generation.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Dakota uses the same bulb size for both high beam and low beam functions across all listed years, as each applicable bulb type is a dual-filament unit that handles both lighting modes within a single housing.
The 9008 bulb is a dual-filament halogen unit operating at 12V with a 65W high beam filament and a 55W low beam filament, fitted with a P26t base. It appears in the Dodge Dakota across the 2005-2010 model years.
The 9007 bulb shares the same 12V, 65W/55W power rating as the 9008 but uses a PX29t base rather than a P26t base, making the two types physically non-interchangeable despite their identical wattage. The 9007 is specified for the 1997-2004 model years.
The 9004 bulb is also a dual-filament halogen unit with a P29t base, but its low beam filament is rated at 45W rather than the 55W found in the 9007 and 9008, giving it a lower output on the low beam setting. It is specified for the 1996 model year and for 1991-1995 models equipped with halogen capsule headlamps.
The H4666 is a rectangular sealed beam unit rather than a replaceable bulb capsule. When this unit fails, the entire assembly is replaced rather than an internal filament component. It is rated at 12V and is listed for the 1987-1990 model years.
For the 1991-1995 Dodge Dakota, two distinct headlamp systems were offered: halogen capsule headlamps using the 9004 bulb and sealed beam headlamps using the H4666 unit. The correct replacement depends on which system is installed, and the two types are not interchangeable with each other.
All four bulb types listed across the Dakota's specifications conform to ANSI standards recognized in both the United States and Canada, indicating standardized sizing and electrical ratings within those markets.
The base types across the three replaceable halogen bulbs, P26t for the 9008, PX29t for the 9007, and P29t for the 9004, are each physically distinct, meaning none of these three bulb sizes can serve as a direct substitute for another despite sharing the same dual-filament halogen design.
