Additional Notes

The Ford Ranger courtesy bulb specifications span model years 1983 through 2004, with three distinct bulb types appearing across that range: the 212-2, 912, 906, and 89.
The 212-2 is the most frequently specified courtesy bulb across the Ford Ranger lineup, covering the 1994 and 1997-2004 model years. It is a festoon-style bulb with an SV8.5 base, 41mm in length, rated at 12V and 12W, and built to ANSI standards for the US and Canadian markets.
The 912 is the second most common bulb type in these specifications, used across the 1986 and 1988-1992 and 1995-1996 model years. It is a T15 wedge bulb rated at 12V and 12W, also conforming to ANSI standards, and is classified as a variant of the 921 bulb.
Because the 912 is a variant of the 921, the two share closely related electrical and physical characteristics, though they are not always interchangeable. Substituting one for the other without confirming fitment compatibility carries a risk of improper seating or electrical mismatch.
The 212-2 festoon bulb uses an SV8.5 base, which is a specific socket type. Wedge-base bulbs such as the 912 and 906 use a fundamentally different mounting method, meaning these two categories are not physically interchangeable with each other or with the 212-2.
The bulb 89 is specified for the Ford Ranger in 1983-1985 and 1987. It uses a BA15s bayonet base and is rated at 12V and 13W. It is described as a lower-wattage variant of the 1156, and its bayonet base distinguishes it from all other bulb types listed in these specifications.
The 906 is specified only for the 1993 Ford Ranger. It is a T10 miniature wedge bulb rated at 12V and 8W, making it the lowest-wattage bulb among those listed. Its T10 form factor is smaller than the T15 of the 912, and the two are not interchangeable.
All four bulb types in these specifications conform to ANSI standards applicable to the US and Canadian markets, indicating consistent regulatory compliance across the full model year range covered.
The 212-2 and 912 share the same voltage and wattage ratings of 12V and 12W, yet their base types differ entirely. The 212-2 uses an SV8.5 festoon base while the 912 uses a wedge mount, so identical electrical ratings do not indicate physical compatibility between the two.
The 89 bulb, at 13W, draws slightly more power than the 212-2 and 912 at 12W, and notably more than the 906 at 8W. These wattage differences reflect the specific circuit and socket requirements of each model year for which a given bulb is specified.
