Toyota Cressida high beam and low beam headlight bulbs utilize 9004, H4651, H6024, H4656, and H4652 sizes depending on configuration and model generation. The replacement chart covers 1978 through 1992 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9004 bulb is a dual-filament halogen type with a P29t base, rated at 12V with a wattage of 65W on high beam and 45W on low beam. Its dual-filament design allows a single bulb to serve both the high beam and low beam functions, which is reflected in the Toyota Cressida's 1985-1992 model years sharing the same 9004 specification across both headlight positions.
The H6024 is a 7-inch round sealed beam unit operating at 12V. Unlike halogen capsule bulbs, sealed beam units integrate the filament, reflector, and lens into one assembly, meaning the entire unit is replaced rather than an internal bulb. The Cressida used this type for both high and low beam positions during the 1978-1980 model years.
The H4651, H4652, and H4656 are all 4x6-inch rectangular sealed beam units operating at 12V, each conforming to ANSI standards for the US and Canadian markets. Like the H6024, none of these accept a replaceable internal bulb; the full sealed unit is the serviceable component.
For the 1981-1984 Toyota Cressida, the low beam position alternates between the H4652 and H4656 depending on the model year, while the high beam position uses the H4651 across all four years. The H4652 is a variant of the H4651, and although both share the same 4x6-inch rectangular sealed beam format, they are not the same unit and are not interchangeable with each other or with the H4656.
The 9004 bulb type is an ANSI-standardized halogen unit, meaning it conforms to a defined specification shared across multiple vehicle manufacturers. However, socket and housing compatibility is determined by the specific vehicle application, and the ANSI designation alone does not confirm fitment across different makes or models.
All bulb types listed across the full 1978-1992 span of the Cressida's headlight specifications are rated at 12V, consistent with standard automotive electrical systems of that period.
The sealed beam units (H4651, H4652, H4656, and H6024) each carry an ANSI designation valid for the US and Canadian markets. This standardization means equivalent sealed beam units from different manufacturers sharing the same ANSI code are generally interchangeable at the unit level, provided the housing accepts the correct physical format.
The transition from sealed beam units to the 9004 halogen capsule bulb in the Cressida's specifications occurred between the 1984 and 1985 model years. From 1985 onward, the 9004 replaced separate high and low beam sealed units with a single dual-filament bulb serving both functions within one housing.
