Additional Notes

The Honda S2000 uses the 168 bulb size for the trunk across the 2000-2009 model years.
The 168 is an ANSI-standardized bulb type, meaning its specifications are defined by a recognized North American industry standard applicable in both the United States and Canada.
The 168 bulb follows the T10 miniature wedge form factor, a designation that refers to its tubular glass envelope and wedge-shaped base, which seats directly into a socket without a separate metal base or pins.
The 168 bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
The 168 bulb carries a rated wattage of 4.9W, placing it in the low-wattage range typical of interior and trunk illumination applications.
Because the 168 uses a wedge base rather than a bayonet or screw base, fitment depends on socket compatibility with the T10 wedge format specifically.
The uniformity of the 168 specification across all ten model years of the Honda S2000 indicates a single socket type was used in the trunk throughout the vehicle's production run.
