The Suzuki X-90 side marker utilizes a 194 bulb size for illumination purposes. Data for the specific component covers the range from 1996 through 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki X-90 uses two distinct bulb sizes for its side marker positions across the 1996-1998 model years: the 194 at the front and the 168 at the rear.
Both the 194 and 168 are ANSI-standardized bulbs recognized in the United States and Canada, meaning they conform to a defined set of electrical and physical specifications rather than being proprietary to the vehicle.
Both bulbs share the T10 miniature wedge form factor, a small, wedge-shaped base design that requires no locking mechanism and is retained by socket tension alone.
Both bulbs operate on a 12-volt system, consistent with standard automotive electrical architecture.
Although the 194 and 168 share the same T10 wedge base, they are not electrically identical. The 194 is rated at 3.78 watts, while the 168 draws 4.9 watts, reflecting a difference in filament resistance and light output.
The wattage difference between the two bulbs means that substituting a 194 for a 168, or vice versa, would result in an incorrect power draw for that socket position, even though the physical base is the same.
The front side marker position on the Suzuki X-90 uses the 194 bulb consistently across all three model years covered in the specifications, from 1996 through 1998.
The rear side marker position uses the higher-wattage 168 bulb across the same 1996-1998 span, indicating the rear marker draws more power than the front.
