ANSI standard (US & Canada). Miniature wedge bulb (T10). 12V, 3.78W.	194

The Honda Odyssey stepwell position uses the 194 bulb size across the 2005-2024 model years.
The 194 bulb is classified under the ANSI standard, which is the recognized designation system for miniature automotive bulbs in the United States and Canada.
This bulb follows the T10 form factor, a miniature wedge-base design that seats without a separate socket lock, relying instead on the tension of the wedge base itself to maintain contact.
The 194 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
The rated wattage of the 194 is 3.78W, placing it in the low-power range typical of interior courtesy and stepwell lighting applications.
The T10 wedge base of the 194 is a widely produced form factor, and direct-fit LED replacements in the same T10 wedge base are commonly available as aftermarket alternatives for this position.
Because the 194 bulb is an ANSI-standardized type, fitment is governed by the T10 wedge base specification rather than by manufacturer-specific socket designs, meaning physical compatibility is consistent across the full 2005-2024 range of the Odyssey for this position.
