Toyota Avalon Bulb Size By Years
I started this bulb size chart because, from personal experience changing bulbs on a 2018 Toyota Avalon, finding the right fit felt slower than it needed to be. Think of it as a simple reference that lists OEM bulb sizes and common aftermarket equivalents, a mental model to speed up your parts hunting and reduce returns.
A small win is seeing a compatible part number and knowing what to order, which often saves a trip to the store. I expand the scope by noting common alternatives and caveats for function and brightness, offering a rule of thumb for matching sockets rather than guessing.
Quick recap: use this list to identify correct bulbs confidently. Affiliate disclaimer: some links may earn me a small commission at no extra cost to you; I include them to keep this guide free and practical.
