Dodge Lancer front and rear turn signal bulbs utilize 3057NA, 2057, 1034, and 1154 bulb sizes depending on location and model variant. The replacement chart covers 1955 through 1989 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 2057 bulb is the most frequently specified size across the Dodge Lancer turn signal data, appearing in both front and rear positions for the 1985-1989 model years, as well as in the rear for those same years exclusively.
The 1034 bulb is the second most recurring specification, covering both front and rear turn signal positions on the 1956-1957 and 1959-1962 Dodge Lancer model years.
The 2057 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a high/low filament draw of 26.9W and 8W respectively, and is noted as a brighter variant of the 1157.
The 1034 shares the same BAY15d bayonet base as the 2057 but operates at a lower wattage of 21W/5W at 12V, making it a less powerful variant of the 1157 family.
The 3057NA is specified exclusively for the front turn signal on the 1988-1989 Dodge Lancer. It is a dual-filament wedge bulb in a T25 form factor with natural amber glass, rated at 12V and 27W/7W.
The natural amber glass of the 3057NA produces a colored output without relying on an amber-tinted lens, which distinguishes it from clear-glass bulbs used in housings with colored lenses.
On the 1988-1989 Dodge Lancer, the front and rear turn signals use different bulb types. The front uses the 3057NA while the rear uses the 2057, meaning the two positions are not interchangeable despite both being dual-filament designs.
The 1154 bulb is specified solely for the 1955 Dodge Lancer in both front and rear turn signal positions. It carries a BAY15d bayonet base and is rated for both 6V and 12V operation, reflecting the transitional electrical systems of mid-1950s vehicles.
Although the 2057 and 1034 share the same BAY15d bayonet base, their differing wattage ratings indicate they are not direct substitutes, as substituting one for the other would alter the electrical load and light output.
The 3057NA and 2057 are both dual-filament bulbs rated at 12V with similar high-beam wattage, but the 3057NA uses a T25 wedge base rather than a BAY15d bayonet base, making them physically incompatible with each other's sockets.
