The Lexus RC200t back up light requires a 921 bulb size for the rear lighting assembly. Data for the specified component covers the period from 2016 through 2017.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 921 bulb follows the ANSI standard, making it the designated type for both the standard and inner back up light positions on the Lexus RC200t across the 2016-2017 model years.
The 921 is a wedge-style bulb, classified under the T15 designation, which refers to its tubular glass envelope size expressed in eighths of an inch.
The bulb operates at 12 volts and draws 16 watts, consistent with conventional incandescent back up light applications in passenger vehicles.
The T15 wedge base connects directly into a socket without a separate metal base or pins, relying on the glass envelope's tapered end to make electrical contact.
The 921 bulb carries ANSI standardization applicable to both the United States and Canada, meaning the specification applies uniformly across North American market RC200t vehicles.
The inner back up light on the 2016 Lexus RC200t carries a production date qualifier, with the 921 bulb size applying to vehicles produced from October 2015 onward.
Both the standard back up light and the inner back up light positions use the same 921 bulb size, indicating interchangeability between the two positions within this vehicle.
