The Chrysler LHS side marker utilizes a 168 bulb size for illumination purposes. Data for 1997 through 2000 provides the specific information regarding the application of 168 bulbs.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chrysler LHS uses two distinct bulb types across its front and rear side marker positions: the 168 and the 3157NA, both of which conform to ANSI standards recognized in the United States and Canada.
The 168 is a miniature wedge bulb in the T10 form factor, rated at 12V and 4.9W. Its single-filament, low-wattage design is typical of side marker and courtesy lighting applications.
The 3157NA is a dual-filament wedge bulb in the T25 form factor, rated at 12V with a 27W/7W output. The natural amber glass envelope gives it a built-in color without the need for a tinted lens or housing.
The rear side marker position on the Chrysler LHS uses the 168 bulb across all model years covered in the specifications, spanning 1994-2001.
The front side marker position follows a split fitment pattern. The 1994-1997 model years use the 3157NA, while the 1999-2001 model years use the 168.
The dual-filament construction of the 3157NA means it carries two separate circuits within a single bulb, which is a functionally different configuration from the single-filament 168. These two types are not interchangeable.
The T10 and T25 designations refer to the tubular bulb body width, measured in eighths of an inch. The T25 body of the 3157NA is physically larger than the T10 body of the 168, which further distinguishes the two in terms of socket fitment.
The 3157NA variant is specifically the natural amber version of the broader 3157 bulb family. A standard 3157 with a clear envelope would produce white light, making the NA suffix a critical distinction for applications requiring amber output.
