Additional Notes

The 9004 bulb is a dual-filament halogen type operating at 12V with a high beam output of 65W and a low beam output of 45W. Its P29t base is a single connector that serves both filaments, making it a self-contained unit for both beam functions within one housing.
Because the 9004 handles both high and low beam functions in a single bulb, the Volvo 760 for model years 1988-1990 lists the same 9004 size under both the high beam and low beam sub-parts. This reflects the dual-filament design rather than two separate bulbs.
The H4651, H4652, and H4656 are sealed beam units conforming to the 4x6-inch rectangular ANSI standard used in North American markets. In a sealed beam design, the reflector, lens, and filament are fused into one glass unit, so the entire assembly is replaced rather than an individual bulb.
For the Volvo 760 in model years 1983-1987, the high beam position consistently uses the H4651 sealed beam unit across all five years, while the low beam position varies between H4652 and H4656 depending on the specific year.
The H4652 is described as a variant of the H4651. Despite sharing the same 4x6-inch rectangular sealed beam format and 12V rating, H4651 and H4652 are distinct part numbers and are not listed interchangeably within the specifications.
The H4656 appears in the low beam position for the 760 in 1983, 1984, and 1986, while H4652 fills the low beam position in 1985 and 1987. Substituting one for the other without confirming fitment would be inconsistent with the specifications as listed.
All bulb types listed across the Volvo 760 headlight specifications conform to ANSI standards applicable to the United States and Canada, indicating these fitments are specific to North American market vehicles.
The transition from sealed beam units to the 9004 halogen bulb occurred between the 1987 and 1988 model years on the 760. Sealed beam technology requires no separate bulb socket, whereas the 9004 requires a compatible wiring harness connector and bulb socket, meaning the two systems are not directly interchangeable.
