Plymouth Cranbrook high beam and low beam headlight bulbs both use the H6006 size. The replacement chart covers 1951 to 1953 production years with 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 listed across all headlight positions in the Plymouth Cranbrook specifications, covering model years 1951-1953.
The H6006 is a 5x7-inch rectangular sealed beam unit operating at 12 volts, built to ANSI standards recognized in both the United States and Canada.
A sealed beam unit integrates the filament, reflector, and lens into a single glass assembly, meaning the entire unit is replaced rather than an internal bulb.
The H6006 serves both the high beam and low beam functions in the Cranbrook, with a dual-filament design inside the sealed unit allowing it to fulfill both roles from a single housing.
The Plymouth Cranbrook (1951-1953) uses the same H6006 specification for both high and low beam positions across all listed model years, indicating no variation in headlight hardware during this production span.
The 5x7-inch rectangular form factor of the H6006 was a standardized size, meaning units from different manufacturers conforming to the same ANSI specification are generally interchangeable with one another.
