Additional Notes

The Honda Odyssey uses the 194 bulb for the interior door position across the 2005-2020 model years, making it the dominant bulb type in these specifications by a wide margin.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, operating under the ANSI standard recognized in both the United States and Canada. Its wedge-style base requires no separate socket retainer, as the bulb body itself locks into the housing.
The 1998 Honda Odyssey uses the DE3021, a festoon-type bulb with a 31mm length and end-cap contacts, also rated at 12V and conforming to ANSI standards.
The 1997 and 1995 model years share the 6428 bulb, a 36mm festoon type with an SV8.5 base rated at 12V and 5W, also an ANSI-standard part.
The DE3021 and 6428 are both festoon bulbs, but they are not interchangeable. The DE3021 measures 31mm in length while the 6428 measures 36mm, and their base configurations differ, with the 6428 using an SV8.5 base and the DE3021 using end-cap contacts.
The 1996 Honda Odyssey uses the 13050, which carries an OEM/Wagner part number rather than an ANSI designation, classifying it as a specialty halogen bulb for a specific application at 12V.
Because the 13050 is identified by a manufacturer part number rather than an industry-wide ANSI code, sourcing a direct equivalent may require cross-referencing Wagner catalog data or OEM parts documentation.
The T10 wedge format of the 194 bulb is widely used across the automotive industry, which means aftermarket and LED replacement options in this size are broadly available for the 2005-2020 Odyssey interior door position.
All four bulb types listed across these specifications operate at 12V, consistent with standard automotive electrical systems.
The shift from varied bulb types in the 1995-1998 model years to the uniform 194 specification from 2005 onward reflects a consolidation to a single standardized bulb for the interior door position in later generations of the Odyssey.
