Additional Notes

The International 8500 TranStar uses the 212-2 bulb for its dome light across the 2008-2011 model years.
The 212-2 is an ANSI-standardized bulb type, meaning its physical and electrical specifications conform to a recognized North American standard shared across the US and Canada.
The 212-2 is a festoon-style bulb, which is a cylindrical lamp that mounts by pressing its two end caps into spring clips rather than using a screw or bayonet socket.
The bulb measures 41mm in length, which is a critical fitment factor since festoon bulbs must match the spacing of the spring clips in the housing.
The 212-2 uses an SV8.5 base, a designation that refers to the 8.5mm width of the end caps on the festoon body.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in most commercial trucks.
The 212-2 draws 12 watts, placing it in the moderate output range for interior dome lighting applications.
When substituting the 212-2 with an alternative festoon bulb, both the 41mm length and the SV8.5 base designation must match to ensure proper fitment in the dome light housing.
