Additional Notes

The Honda CR-Z uses the 194 bulb for its interior door application across all listed model years, spanning 2011-2016.
The 194 is classified as a miniature wedge bulb under the T10 designation, a form factor widely used in low-profile automotive interior sockets.
The T10 wedge base connects to its socket through two metal contacts on the sides of the glass envelope rather than a separate metal base, which allows for tool-free removal by hand.
The 194 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
At 3.78 watts, the 194 draws a relatively low current, which is typical for courtesy and door illumination functions where extended on-time is possible.
The 194 carries ANSI standardization applicable in both the United States and Canada, meaning the designation refers to a consistent specification across both markets.
Because the 194 is an ANSI-standardized type, aftermarket and OEM replacements sold under that number are expected to conform to the same base type, voltage, and wattage as the original fitment in the Honda CR-Z (2011-2016).
When substituting LED replacements for the 194 in T10 wedge sockets, the physical base must match the wedge form factor to seat correctly in the original socket.
