Dodge W250 License Plate Bulb Size

Additional Notes

• The Dodge W250 license plate bulb specifications cover model years 1983-1993 and reference three distinct bulb types: 168, 67, and 1155.
• The 168 bulb is the most frequently specified type across the W250 lineup, appearing in six of the eleven model years covered.
• The 168 is a T10 miniature wedge bulb rated at 12V and 4.9W, conforming to ANSI standards for the US and Canadian markets.
• The wedge base design of the 168 bulb means it is retained by friction rather than a locking mechanism, which distinguishes it from the bayonet-base bulbs also found in this vehicle's history.
• The 67 and 1155 bulbs both use a BA15s single-contact bayonet base, making them physically similar in mounting style despite differing in wattage output.
• The 67 bulb is rated at 12V and 8W, while the 1155 is rated at 12V and 21W, meaning the 1155 draws significantly more power and produces greater light output than the 67.
• Both the 67 and 1155 are described as variants of the 1156 bulb family, though their wattage ratings differ from the standard 1156, and they are not interchangeable with it in applications where wattage tolerance is a factor.
• The 1985 Dodge W250 is the only model year in the covered range specified to use the 1155 bulb for the license plate position.
• Because the 168 wedge base and the BA15s bayonet base are physically incompatible socket types, bulbs from these two groups cannot be substituted for one another without a socket adapter or wiring modification.
• The 67 and 1155 share the same BA15s base, but their wattage difference means a direct substitution between them could affect socket heat tolerance and circuit load in the license plate housing.
