The Honda S2000 side marker utilizes a 12961 bulb size for illumination purposes within the exterior lighting assembly. Data provided for the specific bulb application covers the range from 2000 to 2003.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 168 bulb is the sole bulb type specified for the Honda S2000 across all listed side marker positions and model years.
The 168 bulb follows the ANSI standard recognized in the United States and Canada, placing it within a defined regulatory framework for miniature automotive lighting.
It is a T10 miniature wedge bulb, a form factor that uses a wedge-shaped base rather than a pin or bayonet mount, allowing it to be inserted directly into a compatible socket without rotation.
The 168 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
Its rated wattage of 4.9W places it in the low-power range typical of marker and indicator lighting, which is distinct from higher-draw applications such as headlamps or fog lights.
Both the front and rear side marker positions on the Honda S2000 (2000-2003) share the same 168 bulb specification, meaning the same bulb type serves all four side marker sockets on the vehicle.
The T10 wedge base is a widely used form factor, though fitment compatibility depends on the socket design of the specific vehicle; the 168 and similar T10 bulbs are not universally interchangeable despite sharing a base type.
The 168 designation is an ANSI trade number, a standardized coding system that defines the bulb's electrical and physical characteristics independently of manufacturer branding.
