The Chevrolet Fleetline uses H6006 bulbs for both high beam and low beam headlight applications, with this bulb size representing the standard specification across both lighting functions. The replacement chart covers 1950 to 1952 model years and details the bulb size specifications for vehicle production during this period.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Fleetline uses the H6006 bulb size across all listed model years (1950-1952) for both high beam and low beam headlight positions.
The H6006 is an ANSI-standard sealed beam unit recognized in the United States and Canada, rated at 12 volts.
A sealed beam unit integrates the filament, reflector, and lens into a single glass housing, which means the entire unit is replaced rather than an internal bulb.
The H6006 follows a 5x7-inch rectangular form factor, a standardized shape that was common in mid-century American vehicle headlight systems.
Because the high beam and low beam positions on the Fleetline share the same H6006 specification, a single unit type serves both functions across all listed years.
The ANSI designation of the H6006 indicates it conforms to a defined industry standard, which historically allowed for interchangeability across different vehicle makes that specified the same sealed beam type.
