Additional Notes

The DE3175 is a festoon-type bulb, meaning it is cylindrical in form and makes electrical contact through metal caps at each end rather than through a base socket. It measures 31mm in length and operates at 12 volts.
The DE3175 follows the ANSI standard, which is the recognized specification framework for automotive lighting in the United States and Canada.
The Hyundai Genesis uses the DE3175 bulb for its front stepwell position across the 2009-2014 model years.
The 2014 model year carries a production date qualifier, with the DE3175 fitment applying only to vehicles built up to January 17, 2014. Vehicles produced after that date fall outside this specification.
The end-cap contact design of the DE3175 requires a festoon-style holder. Bulbs with pin-type or wedge-type bases are not interchangeable with this fitment, regardless of similar voltage or size.
