Hyundai Veloster N Map Light Bulb Size

Additional Notes

• The 904 bulb is the map light specification for the Hyundai Veloster N across the 2019-2022 model years listed.
• The 904 bulb follows the ANSI standard recognized in the United States and Canada, classifying it as a regionally standardized automotive component.
• This bulb belongs to the T10 miniature wedge family, a form factor characterized by a wedge-shaped base that seats directly into a socket without a separate metal cap or pins.
• The 904 operates at 12 volts and 8 watts, placing it in the low-wattage range typical of interior courtesy and reading light applications.
• The T10 wedge base is a widely used platform in automotive interior lighting, and multiple bulb types share this base configuration, which introduces substitution compatibility considerations when selecting replacements.
• Although the T10 base is common across many bulb variants, wattage differences between those variants can affect socket heat tolerance and circuit load, making the 8W rating a relevant factor in fitment decisions.
