Dodge Meadowbrook front and rear turn signal bulbs utilize 1154 and 1158 sizes. The replacement chart covers 1950 through 1954 production specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge Meadowbrook uses two bulb types across its model years for turn signal applications: the 1154 and the 1158, both of which are ANSI-standardized for the US and Canadian markets.
Both the 1154 and 1158 are dual-filament bulbs sharing the BAY15d bayonet base, a double-contact base design where the two contact pins are offset to ensure correct orientation during installation.
The 1154 is noted as an older variant of the more widely known 1157 bulb, and unlike the 1158, it carries a 6V/12V rating, meaning it is compatible with either a 6-volt or 12-volt electrical system.
The 1158 is rated for 12V only, which distinguishes it electrically from the 1154 despite the two sharing the same BAY15d base type.
The Dodge Meadowbrook (1951-1954) uses the 1154 bulb for both front and rear turn signals across those four model years.
The 1950 Dodge Meadowbrook uses the 1158 bulb for both front and rear turn signals, setting it apart from the later model years.
Although the 1154 and 1158 share the same BAY15d bayonet base, their differing voltage ratings mean the two bulbs are not straightforward substitutes for one another, and the correct type for each model year warrants attention.
