The American Motors Eagle high beam headlight uses an H4651 bulb size, while low beam headlights use H4656 or H4652 bulb sizes. The replacement chart covers 1980 through 1988 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 American Motors Eagle uses sealed beam headlight units across all listed model years, meaning the lens, reflector, and filament are fused into a single glass assembly. When the filament fails, the entire unit is replaced rather than an internal bulb.
All three headlight types specified for the Eagle, the H4651, H4656, and H4652, conform to ANSI standards recognized in both the United States and Canada. Each operates at 12 volts and shares the same 4x6-inch rectangular form factor.
The H4651 sealed beam serves as the high beam unit for the American Motors Eagle across the 1980-1988 model years, with no variation in that position throughout the listed range.
The low beam position shows a split between two sealed beam types. The H4652 is specified for the 1980, 1981, and 1983 model years, while the H4656 takes over for the 1984-1988 model years.
The H4652 is described as a variant of the H4651. Although both share the same 4x6-inch rectangular sealed beam construction and 12-volt rating, they are not the same unit and serve different positions on the vehicle.
The H4656 and H4651 are distinct sealed beam types despite sharing the same physical size and voltage rating. The H4656 is designated exclusively for the low beam position, and substituting one for the other would not reflect the factory specification.
