Chrysler Newport Headlight Bulb Size

Additional Notes

• The H5001 is the most frequently specified high beam unit across the Chrysler Newport's headlight history, covering model years 1958-1978. It is a 4-inch square sealed beam unit conforming to ANSI standards for the US and Canadian markets, operating at 12V. Like all sealed beam types used on this vehicle, the entire unit is replaced rather than an internal bulb.
• The H5006 holds an equivalent position on the low beam side, specified for model years 1958-1978. It is a 5.75-inch round sealed beam unit, also ANSI-standardized and rated at 12V. Its round form contrasts with the square profile of its high beam counterpart, the H5001, meaning the two are not interchangeable despite sharing the same era of fitment.
• The Chrysler Newport used the H6006 for both high and low beam positions during model years 1950-1955. This unit is a 5x7-inch rectangular sealed beam operating at 12V under ANSI standards. The shared use of a single bulb type for both beam functions in those years reflects a single-headlamp-per-side configuration rather than a separate dual-beam system.
• For 1956-1957, both beam positions specify the H6024, a 7-inch round sealed beam unit rated at 12V. As with the H6006 period, a single unit type covers both high and low beam functions, indicating a continued single-lamp configuration for those two model years.
• A transition in headlight format occurred between the 1957 and 1958 Newport. The 1957 model used the 7-inch round H6024, while the 1958 model shifted to the 4-inch square H5001 for high beam and the 5.75-inch round H5006 for low beam, reflecting the industry-wide adoption of dual sealed beam headlight systems in the United States that took effect for the 1958 model year.
• A further format change is recorded for the 1979-1981 Newport, where the high beam position moved from the 4-inch square H5001 to the 4x6-inch rectangular H4651. The low beam position also shifted during this period, with 1979-1980 using the H4656 and 1981 using the H4652, which is specified as a variant of the H4651. All three rectangular units are ANSI-standardized 12V sealed beam assemblies.
• The H4652 and H4651 are both 4x6-inch rectangular sealed beam units under ANSI standards, with the H4652 described as a variant of the H4651. On the Newport, the H4651 serves the high beam position for 1979-1981, while the H4652 serves the low beam position exclusively in 1981. The two types are not specified as interchangeable, and their distinct beam functions indicate different internal optical configurations despite the shared physical format.
• All headlight units specified for the Chrysler Newport across every model year in these specifications are sealed beam assemblies conforming to ANSI standards applicable in the US and Canada. None of the listed types use a replaceable internal bulb; the optical assembly, reflector, and lens are a single sealed unit that is replaced as a whole when the light fails.
