Audi A5 Bulb Size By Years
Misconception: people think all replacement bulbs fit any car, so matching size isn't important. Why it seems true: many bulbs look similar at a glance, and online stores show generic photos. Think of it as a mental model that glosses over socket types and beam patterns.
What is true: this list gives the common bulb sizes and types for a 2018 Audi A5 so you can pick a correct replacement quickly. The rule of thumb is to compare the listed size with your owner's manual or the bulb itself before buying.
Implications and quick recap: using the right size keeps lighting performance and avoids electrical issues. Quick tests: check the manual, remove the old bulb to compare, or use the list as a starting point.
