Additional Notes

The Ford Ranger uses the 912 bulb size across all listed model years for the dome light position.
The 912 is an ANSI-standardized bulb type, meaning its specifications are governed by a formal industry standard recognized in both the United States and Canada.
The 912 bulb uses a wedge base, designated T15, which refers to a tubular glass envelope with a plastic wedge at the base that friction-fits directly into the socket without a separate metal connector.
The 912 operates at 12 volts and 12 watts, which is consistent with standard automotive electrical systems.
The 912 is a variant of the 921 bulb. These two types share the same T15 wedge form factor and voltage rating, but the 921 is rated at 18 watts, making the two non-identical in power output despite their physical similarity.
Because the 912 and 921 share the same physical base and socket type, the wattage difference is a relevant fitment consideration for the Ford Ranger (2008-2011) and all other listed model years.
The dome light specification is consistent across the 1995-2004 and 2008-2011 model year groups listed, with the 912 bulb applying uniformly throughout.
