The Chrysler Concorde side marker utilizes 168, 916, and 3157 bulb sizes for the lighting components. Data for the specific bulb sizes covers the range from 1995 to 2000.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chrysler Concorde front side marker position uses two closely related bulb types across its model range: the 3157 and the 3157NA. Both are ANSI-standard dual-filament wedge bulbs in the T25 form factor, rated at 12V with a 27W/7W filament configuration.
The key distinction between the 3157 and 3157NA is the glass envelope. The 3157NA features natural amber-tinted glass, while the 3157 uses clear glass. This difference affects the color output of the light without altering the electrical or physical fitment characteristics.
The Chrysler Concorde front side marker used the 3157NA for the 1993-1997 model years, then transitioned to the clear 3157 for 1998-2001, before returning to the 3157NA for 2002-2004.
Because the 3157 and 3157NA share the same T25 wedge base and identical voltage and wattage ratings, they are physically interchangeable. However, substituting a clear 3157 in a position specified for the 3157NA will produce white rather than amber light output.
The rear side marker position on the Concorde uses a different bulb type entirely. The 168 is a single-filament miniature wedge bulb in the T10 form factor, rated at 12V and 4.9W, which is considerably lower in wattage than the dual-filament T25 bulbs used at the front.
The rear side marker specification shifted from the dual-filament T25 family to the single-filament T10 168 bulb between the 1997 and 1998 model years, and the 168 remained the specified rear side marker bulb through 2004.
For the 1995-1997 rear side marker, the Concorde used the 3057, another ANSI-standard dual-filament T25 wedge bulb rated at 12V and 27W/7W. The 3057 and 3157 share the same form factor and wattage ratings but have different filament configurations, which affects their interchangeability in certain socket types.
The 1993-1994 Concorde rear side marker used the 3157 rather than the 3057, meaning the front and rear positions shared the same bulb type in those years, though the front specified the 3157NA variant with amber glass.
All four bulb types listed across the Concorde side marker specifications conform to ANSI standards applicable in both the United States and Canada, indicating consistent regulatory compliance across the full production range.
The T10 and T25 designations refer to the bulb body size, with T10 being the smaller of the two. A 168 T10 bulb is not physically compatible with a socket designed for a T25 bulb such as the 3157, 3157NA, 3057, or their variants.
