The Chrysler LHS front turn signal requires a 3157NA bulb size while rear turn signals use either 3157 or 3057 bulb sizes. The replacement chart covers 1994 to 2001 model years with corresponding bulb size specifications for each production year.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chrysler LHS front turn signal uses the 3157NA bulb across all listed model years from 1994-2001, with the exception of 1998, which is not present in the specifications.
The 3157NA is a dual-filament T25 wedge bulb rated at 12V with a 27W high-filament and 7W low-filament output, distinguished by its natural amber glass envelope, which produces an amber signal without relying on a colored lens.
The rear turn signal of the Chrysler LHS shifted from the 3057 bulb in 1994-1997 to the 3157 bulb in 1999-2001.
Both the 3057 and 3157 share the same T25 wedge form factor and identical 12V, 27W/7W electrical ratings, yet they are not the same bulb and are not confirmed as interchangeable within these specifications.
The 3157 and 3157NA are electrically identical, both rated at 12V and 27W/7W in a T25 wedge format, with the sole difference being the natural amber glass coating present on the 3157NA.
All three bulb types listed, the 3157NA, 3157, and 3057, conform to ANSI standards applicable in both the United States and Canada.
The dual-filament design of these bulbs allows a single unit to serve two functions, typically combining turn signal and parking or running light duties within one housing.
Substituting a 3157 for a 3157NA in the front position of the Chrysler LHS would result in a clear rather than amber light output, which may affect compliance with lighting regulations depending on lens color.
