Additional Notes

The 904 bulb is an ANSI-standard miniature wedge type with a T10 base, rated at 12 volts and 8 watts. The DE3175 is an ANSI-standard festoon bulb with a 31mm length and end-cap contacts, also rated at 12 volts. These two bulb types are physically and electrically incompatible with each other due to their different base designs.
The Hyundai Elantra map light specification shifts between the 904 and DE3175 across its model year range, meaning the correct bulb type is not uniform across all years and must be confirmed before replacement.
Model years 2021-2024 all use the 904 bulb for the map light position.
Model years 2013-2016 use the DE3175 festoon bulb, while the 2017 model year returns to the 904 type, specifically noted for the front position.
The 2019 model year carries a production date qualifier, specifying the 904 bulb for vehicles built from March 21, 2017 onward. This indicates a mid-cycle production change that affects fitment.
The 2007 model year similarly carries a production date qualifier, applying the 904 bulb only to vehicles built from October 31, 2006 onward.
The 1995 model year specifies the DE3175 bulb exclusively for vehicles without a sunroof, indicating that the sunroof configuration on that year may involve a different fitment for the map light position.
