The International R130 uses 198 bulb size for both front and rear turn signal applications. This replacement chart covers 1953 to 1955 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 198 bulb is the sole bulb type listed across all turn signal positions for the International R130, appearing in both front and rear applications for the 1953-1955 model years.
The 198 bulb follows the ANSI standard, meaning it conforms to the American National Standards Institute specifications recognized across the United States and Canada.
The 198 is classified as a miniature wedge bulb in the T5 form factor. The T5 designation refers to a tubular bulb with a width of 5/8 of an inch, and the wedge base means the glass envelope itself acts as the base, with no separate metal shell.
The 198 bulb operates at 12 volts, which is consistent with the standard electrical system voltage found in most conventional automotive applications of that era.
At 2 watts, the 198 bulb draws a very low amount of power, placing it among the lower end of automotive signal bulb outputs.
The International R130 (1953-1955) uses the same 198 bulb specification for both the front and rear turn signals, indicating no distinction in bulb type between the two positions across the listed Light Duty trim.
The Light Duty designation applies to all listed rows for both the front and rear turn signal positions, covering the full 1953-1955 span in the specifications.
