Additional Notes

The Volvo VNL map light uses two distinct bulb types across its model years: the 5008 for 2011-2015 and the 232 for 2005-2010.
The 5008 is an ANSI-standard single-filament bulb with a BA15s bayonet base, operating at 12 volts. The BA15s base features a single contact pin, which distinguishes it from dual-contact bayonet variants and makes it non-interchangeable with those types.
The 5008 is a lower wattage variant of the 1156 bulb. While both share the BA15s bayonet base, the wattage difference means the 1156 is not a direct substitute for the 5008 in this application.
The 232 is an ANSI-standard festoon bulb with an SV8.5 base, rated at 12 volts and 3 watts. Festoon bulbs are held in place by spring-loaded end caps rather than a socket, which is a physically distinct mounting method from the bayonet base used by the 5008.
The SV8.5 designation on the 232 refers to the base width of 8.5 millimeters. Festoon bulbs with differing base widths are not compatible with the same socket, so the base size is a critical factor in fitment for the 2005-2010 model years.
Both the 5008 and 232 conform to ANSI standards recognized in the United States and Canada, indicating standardized physical and electrical specifications within those markets.
