Dodge Magnum front and rear side marker bulbs utilize 194NA or 168 bulb sizes for the front position and 3157 or 168 bulb sizes for the rear position. The replacement chart covers vehicle production spanning 1978 to 2008 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 Magnum front side marker positions for 2005-2008 use the 194NA bulb, while the 1978-1979 models use the 168 bulb.
The 194NA is a T10 miniature wedge bulb rated at 12V and 3.78W, distinguished by its natural amber glass envelope, which produces an amber output without the need for an amber lens or housing.
The 168 is also a T10 miniature wedge bulb, rated at 12V and 4.9W, making it slightly higher in wattage than the 194NA despite sharing the same base type.
Although the 194NA and 168 share the T10 wedge base, the 194NA is not a direct substitute for the 168 in applications requiring a clear bulb, as its amber glass alters the emitted light color.
The rear side marker positions for the Dodge Magnum 2005-2008 use the 3157, a T25 dual-filament wedge bulb rated at 12V with a 27W high filament and a 7W low filament.
The dual-filament design of the 3157 allows it to serve two lighting functions within a single bulb, which is why it is commonly found in positions that combine side marker and turn signal or brake signal duties.
The 3157 uses a T25 wedge base, which is physically larger than the T10 base used by the 194NA and 168, making these bulb families non-interchangeable across positions.
For the 1978-1979 Dodge Magnum, both the front and rear side marker positions share the same 168 bulb specification, whereas the 2005-2008 models use different bulb types front and rear.
All three bulb types listed, the 194NA, 168, and 3157, conform to ANSI standards applicable in both the United States and Canada.
