The Volvo 262 uses H4651 and H5001 bulb sizes for high beam headlights, while low beam headlights require H4656, H4652, or H5006 bulb sizes. The replacement chart covers 1976 through 1981 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volvo 262 uses sealed beam headlight units across all listed model years, meaning the entire lens-reflector-filament assembly is replaced as one unit rather than swapping an individual bulb.
All sealed beam types specified for the Volvo 262 operate on 12V and conform to ANSI standards recognized in both the United States and Canada.
The H4651 is a 4x6-inch rectangular sealed beam unit serving the high beam function on the 262 for model years 1978-1981.
The H4656, a 4x6-inch rectangular sealed beam unit, covers the low beam function for model years 1979-1981, while the H4652, a variant of the H4651 in the same rectangular format, fills the low beam position for the 1978 model year only.
Although the H4651 and H4652 share the same 4x6-inch rectangular sealed beam format, they are distinct ANSI types assigned to different functions and are not interchangeable with each other.
The 1976 Volvo 262 uses a different headlight configuration from later years, with the H5001 (a 4-inch square sealed beam) for high beam and the H5006 (a 5.75-inch round sealed beam) for low beam.
The shift from the 1976 round and square sealed beam units to the rectangular H4651 and H4656 units seen in 1978-1981 reflects a change in headlight housing format, making the 1976 units physically incompatible with the later mounting positions.
