Additional Notes

The 168 bulb is the sole parking light bulb size listed for the Honda CRX across the 1988-1991 model years.
The 168 is classified as a miniature wedge bulb, designated T10 in the international bulb sizing system, where "T" refers to the tubular shape and "10" indicates the width in eighths of an inch.
The wedge base design means the 168 bulb is held in its socket by the tension of the base itself, with no separate metal contact pins or bayonet fittings involved.
The 168 operates at 12 volts and draws 4.9 watts, placing it among the lower-wattage bulbs in automotive applications, consistent with a parking light function rather than a primary illumination role.
The 168 carries ANSI standardization for the US and Canadian markets, meaning its electrical and physical specifications conform to a defined industry standard rather than a proprietary format.
The T10 wedge form factor is shared by several bulb numbers, and not all T10 bulbs are electrically identical, so wattage ratings are a relevant factor when considering substitutions for the 168 in this application.
