Additional Notes

The 904 bulb is a T10 miniature wedge type operating at 12V with an 8W power rating. It uses a wedge base, meaning it is held in place by friction rather than a locking mechanism, and requires no separate socket pins for contact.
The DE3175 and DE3423 are both festoon-type bulbs, which are cylindrical in form and make electrical contact through metal caps at each end. Both operate at 12V and conform to ANSI standards applicable in the US and Canada.
The DE3175 has a 31mm length, while the DE3423 has a 41mm length. Although both are festoon bulbs with the same contact style, the difference in length makes them non-interchangeable with each other.
The Hyundai Accent uses the 904 bulb for the courtesy light in 2021-2022, as well as in 2003 and 2004, making it the most frequently specified bulb across the listed model years.
The 2005 Accent is the only model year in the specifications to use the DE3175 festoon bulb. Substituting a DE3423 in its place would be incorrect due to the 10mm difference in length between the two festoon types.
The Hyundai Accent used the DE3423 festoon bulb for the courtesy light across the 1995-1999 model years. At 41mm, this is the longest bulb specified across all listed years.
The transition from the DE3423 festoon bulb used through 1999 to the 904 wedge bulb used in 2003 and 2004 reflects a change in socket type between those model years, as the two bulbs are mechanically and electrically incompatible with each other.
