Additional Notes

The Ford E-350 dome light draws from three distinct bulb types across its model years: the 912, the 214-2, and the 561, all of which share a 12V, 12W electrical rating.
All three bulb types conform to ANSI standards recognized in both the United States and Canada.
The 912 is a wedge-type bulb in the T15 form factor and is specified for the Ford E-350 across the 1995-1998 model years.
The 912 is a variant of the 921 bulb, meaning the two share closely related specifications, though they are not always interchangeable without verification.
The 214-2 is a festoon-style bulb with an SV8.5 base and a 41mm length, fitted to the E-350 across the 1985-1991 model years.
The 561 is also a festoon-style bulb but uses end-cap contacts rather than an SV8.5 base, and measures 44mm in length, making it physically distinct from the 214-2 despite both being festoon types.
The 561 is specified for the Ford E-350 across the 1975-1980 model years.
Because the 214-2 and 561 are both festoon bulbs yet differ in length and contact type, the two are not interchangeable with each other.
The wedge-mount 912 and the festoon-mount 214-2 or 561 use fundamentally different socket designs, so cross-substitution between wedge and festoon types is not supported by these specifications.
Despite the shift in bulb type across different eras of the E-350, the 12V, 12W power draw remained consistent across all three bulb designations listed.
