Plymouth Laser front turn signal bulbs utilize 1034NA, 2057, or 3057 bulb sizes, while rear turn signal bulbs use 2057 or 3057 sizes. The replacement chart covers 1990 through 1994 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 Plymouth Laser uses three distinct bulb types across its turn signal positions for the 1990-1994 model years: the 1034NA, 2057, and 3057.
The 2057 is the most frequently specified bulb across both front and rear turn signal positions on the Plymouth Laser, appearing in six of the ten total position-year combinations listed.
The 2057 is an ANSI-standard dual-filament bulb rated at 12V with a high-beam filament drawing 26.9W and a low-beam filament drawing 8W, mounted on a BAY15d bayonet base.
The 3057 is a dual-filament wedge bulb of the T25 form factor, rated at 12V with filaments drawing 27W and 7W respectively, and it also conforms to ANSI standards for the US and Canadian markets.
The 1034NA is a dual-filament bulb sharing the BAY15d bayonet base with the 2057 but is distinguished by its natural amber glass envelope, which produces a colored output without the need for an amber lens.
The 1034NA is described as a variant of the 1157 and is rated at 12V, 21/5W, making its wattage draw notably lower than that of the 2057 despite sharing the same base type.
Although the 2057 and 1034NA share the BAY15d bayonet base, their differing wattage ratings and glass coatings mean they are not functionally interchangeable without affecting light output and color.
The 3057 uses a wedge-style base rather than a bayonet base, making it physically incompatible with sockets designed for the BAY15d-based 2057 or 1034NA.
For the 1992 Plymouth Laser, both the front and rear turn signal positions specify the 3057, making it the only model year where a single bulb type covers both positions.
The 1994 Plymouth Laser front turn signal is the sole application of the 1034NA in these specifications, while its rear turn signal uses the 2057, meaning the two positions require different bulb types that year.
