The Chrysler Nassau high and low beam headlight bulbs utilize H6024 and H6006 size specifications for proper illumination. The replacement chart covers 1955 to 1956 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chrysler Nassau uses two distinct sealed beam types across its model years: the H6024 in 1956 and the H6006 in 1955, both conforming to ANSI standards recognized in the United States and Canada.
The H6024 is a 7-inch round sealed beam unit operating at 12V. As a sealed beam, the lens, reflector, and filament are fused into a single assembly, meaning the entire unit is replaced rather than an internal bulb.
The H6006 follows the same sealed beam construction but takes a 5x7-inch rectangular form factor at 12V, making it physically incompatible with housings designed for the round H6024.
On the Chrysler Nassau, both the high beam and low beam positions use the same bulb type within a given model year, with the H6024 serving both functions in 1956 and the H6006 serving both in 1955.
Because the H6024 and H6006 differ in shape, one cannot be substituted for the other despite sharing the same voltage rating and ANSI compliance status.
The shift from a rectangular sealed beam in 1955 to a round sealed beam in 1956 reflects a change in housing geometry between the two model years, which affects the physical fit of any replacement unit.
