Additional Notes

The 1156 bulb is the most widely used type across the Toyota Pickup's turn signal specifications, appearing in both front and rear positions across the majority of model years from 1975 to 1995. It is a single-filament, 12V, 21W bulb with a BA15s bayonet base, conforming to ANSI standards for the US and Canada.
The 1073 bulb shares the same BA15s bayonet base as the 1156 but operates at a significantly lower wattage of 13W rather than 21W. This wattage difference means the two bulbs are not electrically equivalent, and substituting one for the other without accounting for the wattage variance can affect turn signal flash rates due to changes in circuit resistance.
The 1034 bulb, specified for the Toyota Pickup front turn signal in 1975-1978, is a dual-filament type with a BAY15d bayonet base. Its base type is physically distinct from the BA15s base used by the 1156 and 1073, making cross-substitution between these groups mechanically impossible without a socket adapter.
The 1034 bulb operates at 12V with a 21/5W dual-filament output, functioning similarly to the 1157 family. The two filaments serve separate lighting functions within a single housing, which is a fundamentally different design from the single-filament 1156 and 1073 types.
The front turn signal on the Toyota Pickup used the 1034 bulb exclusively in 1975-1978, then transitioned to the 1156 from 1979 onward, with the exception of 1984-1985, which specified the 1073 instead.
The rear turn signal specifications show less consistency than the front, with the 1073 appearing in 1975, 1977-1980, 1985, and 1988, while the 1156 covers the remaining years. These two bulb types share the same BA15s socket but differ in wattage, so the socket itself is physically compatible across those years.
Because the 1156 and 1073 share the BA15s bayonet base, a 1156 bulb can physically seat into a socket designed for a 1073, and vice versa. However, the wattage difference between 21W and 13W means the turn signal flasher unit may not cycle at the correct rate if the wrong wattage bulb is installed.
All three bulb types in these specifications, the 1156, 1073, and 1034, conform to ANSI standards applicable in the US and Canada, indicating standardized sizing and base configurations within those markets.
