Additional Notes

The Hyundai Sonata uses the 158 bulb size for the instrument panel across the 1989-2001 model years.
The 158 is classified as a miniature wedge bulb with a T10 form factor, which refers to a tubular bulb body approximately 10mm wide that connects via a wedge-style base rather than a screw or bayonet fitting.
The 158 bulb operates at 12 volts and draws 3 watts, placing it among the lower-wattage miniature bulbs used in instrument panel applications.
The 158 designation follows ANSI standards recognized in both the United States and Canada, meaning the specification conforms to a defined and regulated bulb standard rather than a proprietary one.
The T10 wedge base format is shared by several other ANSI-coded bulbs, which means physical fitment alone does not confirm electrical compatibility. Voltage and wattage ratings must also match the original specification.
