Ford E-350 Map Light Bulb Size

The Ford E-350 map light requires bulb sizes 211-2, 168, or 105 depending on the specific application and model configuration. A replacement chart documents bulb size specifications across the 1985 to 1998 production range.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The Ford E-350 map light bulb specifications cover model years 1985 through 1998, with three distinct bulb types used across that span: the 211-2, the 168, and the 105.
The 211-2 is the most frequently specified bulb in these records, appearing across six consecutive model years from 1993 to 1998. It is a festoon-style bulb with an SV8.5 base and a 41mm length, rated at 12V and 12W under the ANSI standard.
The 105 bulb is the second most common type in these specifications, covering seven model years from 1985 to 1991, excluding 1992. It is a single-filament bulb with a BA15s bayonet base, rated at 12V and 13W, and is classified as a variant of the 1156 bulb type.
The 168 bulb is specified only for the 1992 Ford E-350 map light. It is a miniature wedge bulb of the T10 type, rated at 12V and 4.9W, making it notably lower in wattage than the other two bulb types used across this model's history.
All three bulb types conform to the ANSI standard applicable in both the United States and Canada, indicating a shared North American fitment classification.
The base types across these three bulbs are not interchangeable. The 211-2 uses an SV8.5 festoon base, the 168 uses a wedge-style T10 base, and the 105 uses a BA15s bayonet base, meaning substitution between model years requires physical socket compatibility.
The wattage difference between the 105 (13W) and the 168 (4.9W) is substantial, reflecting a significant change in power draw between the 1991 and 1992 model years for the same map light position.
The 211-2 and the 105 operate at comparable wattage levels, 12W and 13W respectively, though their base types and physical form factors remain incompatible with one another.
