The Mazda Miata side marker utilizes a 194 bulb size for illumination purposes. Data for the specified component covers the range from 1995 through 1997.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mazda Miata side marker positions use two bulb types across the model's production span: the 194 and the 168, both of which are ANSI-standardized miniature wedge bulbs rated at 12 volts and sharing the T10 form factor.
Despite sharing the same T10 wedge base, the 194 and 168 are not identical. The 194 draws 3.78 watts while the 168 draws 4.9 watts, meaning the two types differ in power consumption and are not direct substitutes for one another.
The front side marker on the Mazda Miata transitioned from the 168 bulb to the 194 bulb between the 1992 and 1993 model years, with the 168 used in 1990-1992 and the 194 used from 1993 onward through 2005.
The rear side marker follows the same transition pattern, with the 168 specified for 1990-1992 and the 194 specified for 1993-1997.
The 194 bulb is the more widely used type across these specifications, covering the front side marker for 1993-2005 and the rear side marker for 1993-1997.
The 168 bulb appears exclusively in the earlier production years, covering both front and rear side marker positions for the 1990-1992 model years.
Both the 194 and 168 carry ANSI standardization applicable to the United States and Canada, indicating conformance to a defined set of electrical and physical tolerances within those markets.
The front side marker specification for the 1998 model year is not present in the data, while all surrounding years from 1993 through 2005 reference the 194 bulb for that position.
