Additional Notes

The 194 bulb is the sole stepwell bulb size listed for the Honda Accord across the 2018-2021 model years.
The 194 bulb follows the ANSI standard, meaning it conforms to a specification recognized across the United States and Canada.
It belongs to the T10 miniature wedge family, a form factor in which the base of the bulb itself acts as the connector by wedging directly into the socket without a separate metal base.
The 194 operates at 12 volts, which is consistent with standard automotive electrical systems.
Its rated wattage of 3.78W places it in the low-power range, typical of interior courtesy and stepwell lighting applications.
The T10 wedge format is shared by a wide range of miniature bulbs, so fitment depends on confirming both the physical socket type and the electrical rating rather than the form factor alone.
