Peterbilt 282 headlight bulbs utilize H5001 size for high beam and H5006 size for low beam applications. Replacement chart data covers 1965 to 1980 production specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Peterbilt 282 uses the H5001 sealed beam unit for high beam headlights across all model years from 1965-1980.
The H5001 is a 4-inch square sealed beam unit operating at 12 volts. It conforms to ANSI standards recognized in both the United States and Canada. Because it is a sealed beam design, the entire unit is replaced rather than an internal filament or bulb.
The low beam headlight position on the Peterbilt 282 uses the H5006 sealed beam unit across all model years from 1965-1980.
The H5006 is a 5.75-inch round sealed beam unit, also rated at 12 volts and conforming to the same ANSI standards as the H5001. Like the H5001, the H5006 is replaced as a complete unit.
The H5001 and H5006 are physically distinct units. The H5001 is square while the H5006 is round, and the two are not interchangeable between the high beam and low beam positions.
Both the H5001 and H5006 share the same 12-volt electrical rating, meaning both positions operate on a standard 12V automotive electrical system.
ANSI standardization of both units means that any H5001 or H5006 sealed beam from different manufacturers produced to that standard will share the same form and fit, provided the correct designation is matched to the correct position.
