Plymouth Deluxe high beam and low beam headlight bulbs both utilize the H6006 bulb size. The replacement chart covers 1950 to 1951 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6006 is the sole bulb type specified across all listed positions and years for the Plymouth Deluxe, covering both high beam and low beam headlight functions for 1950-1951.
The H6006 is a 5x7-inch rectangular sealed beam unit operating at 12 volts, conforming to ANSI standards recognized in both the United States and Canada.
A sealed beam unit integrates the filament, reflector, and lens into a single non-serviceable assembly, meaning the entire unit is replaced rather than an internal bulb component.
The H6006 serves a dual-function role in the Plymouth Deluxe, with the same part number specified for both the high beam and low beam positions, indicating a shared sealed beam unit handles both lighting modes.
The rectangular form factor of the H6006 is a defining fitment characteristic, as sealed beam headlights were produced in standardized shapes and sizes, making the 5x7-inch rectangular profile a critical compatibility factor when sourcing a replacement unit.
