The Pontiac Silver Streak front and rear turn signal bulbs both utilize a 1154 size bulb for proper operation. The replacement chart covers 1950 to 1952 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 1154 bulb is the sole turn signal bulb type specified for the Pontiac Silver Streak across all listed model years and positions.
The 1154 is an ANSI-standardized bulb recognized in both the United States and Canada.
As a dual-filament bulb, the 1154 supports two separate brightness levels within a single unit, which is typical for automotive applications requiring both running light and turn signal functions from one bulb.
The 1154 uses a BAY15d bayonet base, a two-pin offset bayonet mount 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, meaning the two types share a similar design lineage but are not directly interchangeable without verification of voltage and socket compatibility.
The 1154 is rated for both 6V and 12V electrical systems, reflecting the transitional period in automotive electrics during the early 1950s when some vehicles still used 6-volt systems.
The Silver Streak's front and rear turn signal positions for 1950-1952 share the same 1154 bulb specification, indicating a uniform fitment across both ends of the vehicle throughout those years.
