2020 Toyota RAV4 Bulb Size

Misconception: many people think bulbs are interchangeable between cars, so any LED or halogen will work. It seems true because small sockets look similar and lighting tech often shares names. I say this from swapping bulbs on my own 2020 Toyota RAV4 and seeing fitment surprises. What is true is that each fixture on a 2020 RAV4 usually needs a specific bulb size and type. Think of it as a simple mental model: headlight, fog, turn, and brake each have a rule of thumb for size. This list exists to match those sockets with the right replacements and avoid fitment headaches. Implications are practical—buying the wrong bulb can cost time and returned parts. Quick tests include checking the owner’s manual, comparing part numbers on the removed bulb, and testing fit before final installation. Quick recap: use the chart as a guidance tool.
