Dodge Neon front and rear turn signal bulbs utilize 3457NA, 4157NA, 5702AK, and 3157 bulb sizes across different positions. The replacement chart covers 1995 through 2005 model 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 Neon uses the 3157 bulb for the rear turn signal across all model years from 1995-2005, making it the most consistently specified bulb in these listings. It is an ANSI-standard dual-filament wedge bulb in the T25 form factor, rated at 12V with a 27W high filament and 7W low filament.
The front turn signal position shows variation across the production run of the Dodge Neon, with four distinct bulb designations specified depending on the model year: 3157NA, 4157NA, 5702AK, and 3457NA.
The 3157NA, 3457NA, and 4157NA bulbs share identical electrical ratings of 12V and 27W/7W and all occupy the same T25 wedge form factor. Each carries natural amber glass rather than a clear envelope, which produces the amber signal color without relying on a colored lens.
Despite their shared physical and electrical characteristics, the 3157NA and 4157NA are distinct ANSI part numbers. These designations indicate differences in the internal filament geometry or contact configuration, which affects fitment and interchangeability even when wattage and voltage ratings are the same.
The 5702AK, specified for the 2000 front turn signal, is a Sylvania-specific part number rather than an ANSI standard designation. It corresponds to a coated variant of the 3157 bulb, where an amber coating on the glass envelope serves the same function as the natural amber glass used in the NA-suffix bulbs.
The 3157 rear turn signal bulb has a clear glass envelope, unlike the amber-glass 3157NA used at the front. The amber color for the rear signal on the Neon is therefore produced by the lens assembly rather than the bulb itself.
The front turn signal for model years 1995-1999 used the 3157NA, while 2001-2002 used the 4157NA and 2003-2005 used the 3457NA. These are not interchangeable designations despite sharing the same wattage, as each ANSI number encodes a specific contact and filament configuration.
Substituting a clear 3157 for an NA-suffix bulb in the front position would alter the color output of the turn signal, since the amber tint in NA bulbs is integral to the glass rather than dependent on the housing.
