The Toyota Starlet front and rear turn signal bulbs both utilize a 1156 size bulb for proper operation. The replacement chart covers vehicle production spanning 1981 to 1984 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Toyota Starlet uses the 1156 bulb for both front and rear turn signals across the 1981-1984 model years.
The 1156 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized industry standard used across the United States and Canada.
As a single-filament bulb, the 1156 is dedicated to one lighting function at a time, which contrasts with dual-filament types that serve two functions such as braking and running light simultaneously.
The 1156 uses a BA15s bayonet base, where "BA15s" denotes a bayonet mount with a 15mm base width and a single contact pin, making it a distinct fitment that is not interchangeable with dual-contact bayonet bases such as the BA15d.
The 1156 operates at 12 volts and draws 21 watts, which is consistent with standard automotive electrical systems of that era.
Because the same bulb number applies to all four turn signal positions on the Toyota Starlet across all four listed model years, a single bulb type services the entire turn signal system of the vehicle.
