Chevrolet Two-Ten Series front and rear turn signal bulbs utilize 1034 and 1154 bulb sizes across both locations. The replacement chart covers 1953 through 1957 vehicle production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1034 and 1154 bulb types appear across all listed model years of the Chevrolet Two-Ten Series, covering both front and rear turn signal positions.
The 1034 is an ANSI-standard dual-filament bulb rated at 12V and 21/5W, fitted with a BAY15d bayonet base, and is classified as a variant of the 1157.
The 1154 is also an ANSI-standard dual-filament bulb with a BAY15d bayonet base, though it is designated an older variant of the 1157 and carries a 6V/12V rating rather than a fixed 12V rating.
The Chevrolet Two-Ten Series used the 1034 bulb for both front and rear turn signals across the 1955-1957 model years.
The 1154 bulb was specified for both front and rear turn signals on the 1953-1954 model years.
A bulb change occurred between the 1954 and 1955 model years, when the specification shifted from the 1154 to the 1034 for both front and rear positions simultaneously.
Both the 1034 and 1154 share the BAY15d bayonet base, which is a double-contact offset-pin base commonly associated with dual-filament automotive bulbs.
Despite the shared base type, the 1034 and 1154 are not confirmed interchangeable, as their voltage and wattage ratings differ, and each is listed as a distinct ANSI-standard type.
The dual-filament construction of both bulb types indicates that a single bulb served two functions within the lamp assembly, typically combining turn signal and running or brake light operation.
The 1157, of which both the 1034 and 1154 are variants, is a widely referenced BAY15d dual-filament bulb, placing these specifications within a recognized family of automotive lighting standards.
