Additional Notes

The Kia Telluride map light draws from two distinct bulb families across its model years: the T10 miniature wedge type (904) and the festoon type (DE3425 and DE3423).
The 904 bulb is a T10 miniature wedge rated at 12V and 8W, conforming to ANSI standards for the US and Canadian markets. It is used in the 2024 Telluride.
The DE3425 and DE3423 are both 41mm festoon bulbs operating at 12V with end-cap contacts, also conforming to ANSI standards. They are used across the 2021-2023 model years.
Festoon bulbs make electrical contact through metal caps at each end rather than through a wedge base, which means they are physically and electrically incompatible with the T10 wedge socket used in the 2024 model.
The DE3425 and DE3423 share the same 41mm length and end-cap contact design, though they carry different ANSI designations, indicating a distinction in filament or performance characteristics despite their similar physical form.
Because the 2021 model uses the DE3423 while the 2022-2023 models use the DE3425, substituting one for the other warrants attention to the specific ANSI designation rather than relying solely on physical fit.
