Additional Notes

The 6428 is the most frequently specified interior door bulb for the Honda Passport, covering model years 1994 and 1996-1999, as well as 2001-2002.
The 6428 is a festoon-type bulb operating at 12 volts and 5 watts, with an SV8.5 base and a 36mm length.
Festoon bulbs are cylindrical lamps that mount horizontally between two spring-clip contacts, a common configuration in automotive interior lighting housings.
The DE3021 is also a festoon bulb but uses end-cap contacts rather than an SV8.5 base, and measures 31mm in length, making it physically shorter than the 6428.
The 1995 Honda Passport specifies the DE3021, which is not interchangeable with the 6428 due to the difference in both length and contact type.
The 13050 is identified by an OEM/Wagner part number rather than an ANSI standard designation, indicating it is a manufacturer-specific reference rather than a universally catalogued bulb code.
The 2000 Honda Passport specifies the 13050, a 12-volt halogen bulb intended for a specialty application, setting it apart from the festoon bulbs used in surrounding model years.
The SV8.5 base on the 6428 refers to a festoon base with a specific 8.5mm contact width, a detail relevant when confirming socket compatibility in the door housing.
