Additional Notes

The DE3022 is an ANSI-standardized festoon bulb rated at 12V with a 31mm length and end-cap contacts. It serves as the glove box bulb for the Honda Prelude across the 1988-1991 model years.
The 6428 is an ANSI-standardized festoon bulb rated at 12V and 5W, with a 36mm length and an SV8.5 base. It is the most frequently specified glove box bulb across the Honda Prelude model range, covering 1980 and 1983-1986.
Festoon bulbs make contact through their end caps or base rather than through a screw or wedge fitting, which is a relevant distinction when handling physical installation.
The DE3021, specified for the 1982 Honda Prelude, shares the same 31mm length and end-cap contact design as the DE3022 but carries a different ANSI designation, indicating the two are not interchangeable despite their physical similarities.
The 6428 is 5mm longer than both the DE3021 and DE3022. Festoon bulbs must match the socket length of the housing, so the 36mm 6428 and the 31mm DE-series bulbs are not interchangeable.
The 13050 is identified by an OEM/Wagner part number rather than an ANSI standard designation, classifying it as a specialty halogen bulb for specific applications. It is specified for the 1979, 1981, and 1987 Honda Prelude.
All four bulb types across the full Honda Prelude glove box specification range operate at 12V, consistent with standard automotive electrical systems.
