Jeep Wagoneer front side marker bulbs utilize 97, 158, or 194 size configurations, while rear side marker bulbs require 194 size bulbs. The replacement chart covers vehicle production spanning 1972 to 1990 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Jeep Wagoneer front side marker position uses three distinct bulb sizes across its model years: the 97, 158, and 194.
The 97 bulb is a single-filament type with a BA15s bayonet base, rated at 12V and 13W. It is a variant of the 1156 bulb family and carries ANSI standardization for both the US and Canada. The Jeep Wagoneer front side marker uses this bulb for model years 1985-1990.
The BA15s bayonet base on the 97 bulb is a single-contact fitting, meaning it is not interchangeable with dual-contact bayonet bases used on other bulb types.
The 158 bulb is a miniature wedge type in the T10 form factor, rated at 12V and 3W. The Jeep Wagoneer front side marker uses this bulb for the 1983-1984 model years.
The 194 bulb shares the same T10 miniature wedge form factor as the 158 but operates at a slightly higher wattage of 3.78W at 12V. Both carry ANSI standardization for the US and Canada.
Although the 158 and 194 share the T10 wedge form factor, their wattage ratings differ, and they are not designated as direct substitutes within these specifications.
The front side marker on the Wagoneer used the 194 bulb across model years 1972-1982, representing the longest continuous bulb fitment in the front side marker position.
The rear side marker position on the Wagoneer uses the 194 bulb exclusively across all listed model years, spanning 1983-1990.
For the 1983-1984 model years, the front and rear side marker positions require different bulb sizes. The front uses the 158 while the rear uses the 194, despite both being T10 wedge bulbs.
For model years 1985-1990, the front side marker uses the 97 with a bayonet base, while the rear side marker uses the 194 wedge type, making the two positions mechanically incompatible with each other.
