Additional Notes

The Hyundai Scoupe trunk uses two distinct bulb sizes across its production run: the DE3423 for 1993-1995 and the DE3022 for 1991-1992.
Both the DE3423 and DE3022 are festoon-type bulbs, meaning they are cylindrical in form and make electrical contact through metal caps at each end rather than through a base socket.
The DE3423 has a 41mm length, while the DE3022 measures 31mm, making the two bulbs physically incompatible with each other despite sharing the same festoon contact style and 12V operating voltage.
Both bulbs conform to ANSI standards applicable in the United States and Canada, indicating they meet a defined set of electrical and physical tolerances for those markets.
The 10mm difference in length between the DE3423 and DE3022 is a critical fitment factor, as festoon bulbs must span the full distance between their end contacts to seat correctly and maintain a circuit.
Installing a DE3022 in a 1993-1995 Scoupe trunk housing designed for the DE3423 would result in a bulb too short to bridge the contact points, preventing proper function.
