Additional Notes

The International 4400LP uses the 212-2 bulb for its dome light across the 2011-2016 model years.
The 212-2 is a festoon-style bulb, meaning it is cylindrical in shape and mounts by pressing between two spring clips rather than inserting into a socket.
The 212-2 has a length of 41mm, which is a standard festoon size widely used in commercial vehicle interior lighting.
The bulb uses an SV8.5 base, a designation that refers to the end-cap width of 8.5mm on a festoon-type bulb.
The 212-2 operates at 12 volts and draws 12 watts, consistent with standard 12V electrical systems found in medium-duty commercial trucks.
The 212-2 carries ANSI standardization, meaning it conforms to specifications recognized in both the United States and Canada.
Because the 212-2 is an ANSI-standardized part, replacement bulbs from multiple manufacturers are generally interchangeable as long as they match the 41mm length, SV8.5 base, 12V rating, and 12W rating.
Festoon bulbs of the same length but different base designations, such as SV7 or SV10, are not compatible with the SV8.5 socket and would not seat correctly in the International 4400LP dome light housing.
