Audi TT Bulb Size By Years
When I first needed replacement bulbs for my 2018 Audi TT, I felt unsure which sizes matched each socket; think of it as a quick map to the car's lighting. The bulb size chart here gives that map, a simple reference that helped me swap a fog lamp in minutes and build confidence for bigger jobs.
As you scan the chart, the mental model is: light type → socket size → replacement code. I expanded from one small win to checking headlights, indicators, and interior lamps, refining choices by comparing fit and brightness. I validated bulbs by testing fit and beam before final installation.
Quick recap: use the chart as a rule of thumb and double-check fitment notes. Disclosure: links on this page may earn me a small commission at no extra cost to you.
