Plymouth Cambridge high beam and low beam headlight bulbs both utilize the H6006 size. The replacement chart covers vehicle production spanning 1951 to 1953.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Plymouth Cambridge uses the H6006 bulb type across all listed model years (1951-1953) for both high beam and low beam headlight positions.
The H6006 is an ANSI-standard sealed beam unit recognized in both the United States and Canada, operating at 12 volts.
Sealed beam units such as the H6006 house the filament, reflector, and lens within a single fused glass assembly, meaning the entire unit is replaced rather than an internal bulb.
The H6006 follows a 5x7-inch rectangular form factor, which is a standardized size shared across many vehicle applications of that era, making cross-brand fitment possible in some cases.
Because the Plymouth Cambridge (1951-1953) uses the same H6006 specification for both the high beam and low beam positions, the two headlight functions are served by a single sealed beam type rather than separate bulb types for each function.
