Additional Notes

The Honda CR-Z uses the 194 bulb for the stepwell position across all listed model years, spanning 2011-2016.
The 194 is classified as a miniature wedge bulb, following the T10 form factor, which refers to a tubular bulb body approximately 10mm wide with a wedge-style base that connects without a separate socket pin.
The 194 operates at 12 volts and draws 3.78 watts, placing it among the lower-wattage bulbs found in automotive interior and courtesy lighting applications.
The 194 designation follows the ANSI standardization system, meaning the bulb conforms to a defined specification recognized across the United States and Canada.
Because the 194 is an ANSI-standardized T10 wedge type, it shares physical and electrical compatibility with several other bulbs in the same family, though substitutions should be verified against the original wattage and voltage ratings before use.
The wedge base design of the T10 format means the bulb is retained by friction within its socket rather than by a bayonet or screw mechanism, which is a common trait in stepwell and courtesy light positions.
