The Suzuki Swift side marker utilizes a 168 bulb size for the specific lighting component located on the exterior of the vehicle. Data for the bulb covers the range from 1995 through 2001.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki Swift uses the 168 bulb as the dominant side marker fitment across both front and rear positions, covering model years 1990-2001 for the front and 1989-2001 for the rear.
Both the 168 and 194 bulbs share the same T10 miniature wedge base and 12V operating voltage, placing them in the same physical bulb family under ANSI standards applicable to the US and Canadian markets.
Despite their shared base type, the 168 and 194 are not rated at the same wattage. The 168 operates at 4.9W while the 194 operates at 3.78W, meaning the two bulbs draw different amounts of power from the vehicle's electrical circuit.
The 1989 Suzuki Swift front side marker is the sole position in these specifications that calls for a 194 bulb rather than a 168, setting it apart from every other year and position listed.
The rear side marker position on the 1989 Suzuki Swift uses a 168 bulb, which differs from the 194 specified for the front side marker of the same model year, meaning the front and rear positions are not interchangeable for that year.
The T10 wedge base format used by both bulb types is a tool-free, push-in fitment, which is a standard characteristic of miniature wedge bulbs in automotive applications.
Because the 168 and 194 share the same T10 wedge base, physical installation is possible with either bulb in either socket, but the wattage difference means electrical load and light output would not match the original specification if substituted.
