The Chrysler E Class high beam headlight uses an H4651 bulb size, while low beam headlights use H4652 or H4656 bulb sizes. The replacement chart covers 1983 to 1984 vehicle 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 H4651, H4652, and H4656 bulb types are all ANSI-standardized sealed beam units recognized across the United States and Canada, operating at 12 volts.
All three bulb types share a 4x6-inch rectangular sealed beam form factor, which was a regulated standard format widely used in North American automotive lighting during this era.
Sealed beam units of this type are not serviceable at the bulb level. When a unit fails, the entire sealed assembly requires replacement rather than an internal bulb component.
The Chrysler E Class uses the H4651 for the high beam headlight position across both the 1983 and 1984 model years.
The H4652 is described as a variant of the H4651. Despite their shared physical format and voltage rating, these two types are not the same part and serve different beam positions.
The low beam headlight position on the Chrysler E Class changed between model years. The 1983 model uses the H4656, while the 1984 model uses the H4652, making year-specific fitment verification necessary for this position.
Because the H4651 and H4652 share the same 4x6-inch rectangular sealed beam housing, there is a risk of substitution errors. Their designations reflect different optical and photometric configurations suited to distinct beam functions.
