Additional Notes

The International WorkStar 7600 uses the 212-2 bulb for its dome light across all listed model years from 2008-2017.
The 212-2 is classified as a festoon bulb, meaning it is a cylindrical lamp that mounts by pressing its flat end caps into spring-loaded clips rather than using a screw or bayonet socket.
The 212-2 carries an SV8.5 base designation, which refers to the 8.5mm width of its end caps and is the standard base type for festoon bulbs in this size class.
The bulb has a 41mm length, which is the contact-to-contact span that must match the fixture's clip spacing for proper fitment in the International WorkStar 7600.
The 212-2 operates at 12 volts, consistent with the standard electrical system voltage found in commercial trucks.
The bulb carries a 12-watt power rating, which reflects its energy draw at the rated voltage and determines the heat output within the dome light housing.
The 212-2 conforms to ANSI standards recognized in both the United States and Canada, indicating it meets a defined set of dimensional and performance specifications for those markets.
Because festoon bulbs are sized by their length, a replacement must match the 41mm specification exactly, as a shorter or longer festoon will not seat correctly in the spring clips of the WorkStar 7600 dome fixture.
