Fourth generation (XP210, 2020-present) · Supermini / small hatchback
The fourth-generation Toyota Yaris (XP210) is mildly CANbus-sensitive, and interior sockets on this brand rarely throw errors after a straight LED swap, so standard LED bulbs are usually fine. Change the whole cabin set at once, because LEDs are commonly 6000K bright white and look odd beside stock bulbs.
First generation (XP210, 2021-present) · Subcompact / B-segment SUV
Interior LED bulbs in the Toyota Yaris Cross are a size-code exercise first and a CANbus exercise second. Get the bulb code right (194, T10, festoon 31 or 36 or 42 mm, W5W or C5W), then decide whether CANbus-decoded bulbs are worth the small extra outlay given that this car is mildly CANbus-sensitive.
Fifth generation (XA50, 2019-present) · Family SUV / C/D-segment 4x4
The Toyota RAV4 is mildly CANbus-sensitive, and interior sockets on this brand rarely throw errors after a straight LED swap, so standard LED bulbs are usually fine. Replace the whole cabin set together, since LEDs are commonly 6000K bright white and stand out against stock incandescent bulbs.
