Chrysler Laser high beam headlight bulbs use H4651 size while low beam headlight bulbs use H4652 size. The replacement chart covers 1984 to 1986 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 Chrysler Laser uses H4651 and H4652 sealed beam units for high beam and low beam headlights respectively across its 1984-1986 model years.
Both the H4651 and H4652 are ANSI-standardized sealed beam units recognized in the United States and Canada, meaning they conform to a defined performance and physical standard shared across multiple vehicle manufacturers.
Each unit measures 4x6 inches in a rectangular form factor, which was a common sealed beam format in North American automotive lighting during this period.
The H4652 is a variant of the H4651, with the primary distinction being its designation for low beam output rather than high beam use.
Because both types are sealed beam units, the entire assembly is replaced rather than an internal filament or capsule, as there is no separate replaceable bulb component within the housing.
Both units operate at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this type.
The shared 4x6-inch rectangular format between the H4651 and H4652 means the physical housing size is identical, though the two types are not interchangeable due to their differing beam pattern designations.
