Toyota Pickup front side marker bulbs utilize 168, 194, or 89 bulb sizes, while rear side marker bulbs require 1034 size. The replacement chart covers 1975 through 1995 vehicle production years 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 Toyota Pickup front side marker position uses three distinct bulb types across its model years: the 168, 194, and 89, each belonging to different base and filament categories.
The 168 and 194 are both T10 miniature wedge bulbs operating at 12V, though they differ in wattage. The 168 draws 4.9W while the 194 draws 3.78W, making them non-interchangeable despite sharing the same base type and physical form factor.
The Toyota Pickup front side marker uses the 168 bulb for 1993-1995 and the 194 for 1986-1992. Although both are T10 wedge types, substituting one for the other would result in a wattage mismatch with the original specification.
The 89 bulb, specified for the front side marker on 1975-1983 models, is a single-filament bulb with a BA15s bayonet base rated at 12V and 13W. It is described as a lower wattage variant of the 1156 and is not compatible with the wedge-style sockets used in later model years.
The 1034 bulb, used in the rear side marker position for 1975-1983, is a dual-filament bulb with a BAY15d bayonet base rated at 12V with a 21/5W output. It is a variant of the 1157 and its dual-filament design distinguishes it from the single-filament 89 used at the front.
The BAY15d base of the 1034 and the BA15s base of the 89 are physically similar bayonet-style fittings but are not interchangeable. The BAY15d has offset pins to accommodate dual-filament operation, while the BA15s has symmetrical pins for single-filament use.
All four bulb types listed across these specifications conform to ANSI standards applicable in both the United States and Canada, indicating standardized electrical and physical tolerances across the range.
Rear side marker data in these specifications covers only 1975-1983, while front side marker data extends through 1995, reflecting a difference in the scope of rear versus front position coverage within the provided fitment records.
