The Dodge W200 front turn signal uses bulb sizes 1157, 1034NA, or 1157NA, while the rear turn signal requires either 1157 or 198 size bulbs. The replacement chart covers 1975 through 1980 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 Dodge W200 front and rear turn signal positions draw from three distinct bulb types across the 1975-1980 model years: the 1157, 1034NA, 1157NA, and 198.
The 1157 is a dual-filament bulb rated at 12V and 21W/5W, fitted with a BAY15d bayonet base. Its dual-filament design allows it to serve both turn signal and running light functions within a single housing.
The 1034NA and 1157NA are natural amber glass variants that share the same BAY15d bayonet base and 12V, 21W/5W electrical ratings as the standard 1157. The amber glass produces a colored output without relying on a tinted lens.
The 198 is a miniature wedge bulb of the T5 form factor, rated at 12V and 2W. Its single-filament, low-wattage design contrasts sharply with the dual-filament 1157-series bulbs used elsewhere in the same vehicle.
The Dodge W200 front turn signal used the 1034NA for the 1977-1978 model years. This bulb is described as a variant of the 1157, sharing its base type and wattage but distinguished by its natural amber glass envelope.
The 1157NA appeared exclusively on the 1976 front turn signal position. Although electrically identical to the 1157, it is a separate ANSI designation and is not listed as interchangeable with the 1034NA despite their shared characteristics.
The rear turn signal on the Dodge W200 used the low-wattage 198 wedge bulb across the 1975-1978 model years, while the front position used higher-wattage dual-filament bulbs during that same period, indicating the two positions were not electrically matched.
For the 1979-1980 model years, both the front and rear turn signal positions on the Dodge W200 converged on the same bulb, the 1157, making those the only years in the listed range where front and rear positions share an identical specification.
The BAY15d bayonet base is common to the 1157, 1034NA, and 1157NA. However, substituting one for another across different model years should account for the presence or absence of the amber glass coating, as lens and regulatory requirements may differ.
The 198 wedge bulb is physically and electrically incompatible with the BAY15d socket used by the 1157-series bulbs. The two types require different socket designs and cannot be interchanged.
