Additional Notes

The 1154 is the sole parking light bulb size listed for the Chevrolet Fleetline across the 1950-1952 model years.
The 1154 is an ANSI-standardized bulb type recognized in both the United States and Canada.
It is a dual-filament bulb, meaning it contains two separate filaments within a single envelope, allowing it to serve more than one lighting function.
The 1154 uses a BAY15d bayonet base, a two-pin offset base type where the two pins are positioned at different heights to ensure correct orientation during installation.
The 1154 is noted as an older variant of the 1157 bulb, which means the two types share a related design lineage but are not the same part.
The 1154 is rated for both 6V and 12V electrical systems, reflecting the transitional period in automotive electrical standards during the early 1950s.
Because the 1154 and 1157 are related but distinct variants, substituting one for the other without confirming compatibility with the Fleetline's specific socket and voltage system carries a fitment risk.
