Additional Notes

The Hyundai Accent map light uses three distinct bulb types across its model years: the 904, the 168, and the DE3423, each with different physical forms and electrical characteristics.
The 904 and 168 are both T10 miniature wedge bulbs operating at 12V, but they differ in wattage. The 904 draws 8W, while the 168 draws 4.9W, making them electrically incompatible despite sharing the same base form factor.
The 2021-2022 Hyundai Accent map light takes the 904 bulb, while the 2019-2020 model years use the lower-wattage 168 bulb. Although both are T10 wedge types, substituting one for the other is not a direct equivalent swap due to the wattage difference.
The DE3423 is a festoon-style bulb with a 41mm length and end-cap contacts, which is a fundamentally different physical format from the T10 wedge. It is not interchangeable with either the 904 or the 168 under any fitment condition.
The 1995-1999 and 2003-2005 Accent model years all use the DE3423 festoon bulb for the map light position. All three specifications, the 904, 168, and DE3423, conform to ANSI standards applicable in the US and Canada.
