Ford Deluxe front and rear turn signal bulbs both utilize a 1154 size bulb for proper operation. The replacement chart covers 1950 to 1951 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 Ford Deluxe uses the 1154 bulb across both front and rear turn signal positions for the 1950-1951 model years.
The 1154 is a dual-filament bulb, meaning it serves two lighting functions within a single unit, typically combining turn signal and running light or stop light duties.
The 1154 uses a BAY15d bayonet base, which is an offset twin-pin mount designed to prevent incorrect installation by ensuring the bulb seats in only one orientation.
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 operated on 6-volt systems.
The 1154 is classified as an ANSI standard bulb recognized in both the United States and Canada.
The 1154 is an older variant of the more widely known 1157 bulb. While both share the BAY15d base and dual-filament design, they are not directly interchangeable due to differences in filament wattage and voltage ratings.
