Additional Notes

The Honda Prelude courtesy bulb specifications cover model years 1992-2001 and reference two bulb types: DE3022 and DE3175.
Both the DE3022 and DE3175 are festoon-style bulbs, meaning they are cylindrical in shape and make electrical contact through metal caps at each end rather than through a base socket.
Both bulb types share a 31mm length and operate at 12 volts, which reflects the standard low-voltage DC electrical system found in passenger vehicles of this era.
Both the DE3022 and DE3175 conform to ANSI standards applicable to the US and Canadian markets.
Despite their physical and electrical similarities, the DE3022 and DE3175 are listed as distinct part numbers, and the specifications treat them as separate fitments depending on the model year.
The Honda Prelude (1997-2001) uses the DE3022 bulb for the courtesy light position.
The Honda Prelude (1992-1996) uses the DE3175 bulb for the courtesy light position.
A change in the specified bulb type occurs between the 1996 and 1997 model years, coinciding with a generational change in the Prelude's body style.
Because the DE3022 and DE3175 share the same length and voltage rating, physical fitment in the housing may be possible for either type, but the specifications designate a distinct bulb per model year range and substitution is not indicated within the provided data.
