Audi TT Bulb Size By Years

Starting point: I built this bulb size chart after changing bulbs on my 2015 Audi TT and wanting a simpler reference. Think of it as a compact mental model that lists the exact bulb types for headlights, turn signals, and interior lamps so you stop guessing at the parts store. My first quick win was finding the right headlight bulb in minutes instead of driving around. Expand scope and refine: I organized the list by function and location, then confirmed fitment against the owner's manual and a test fit on the car. A useful rule of thumb I learned is to double-check socket shape, not just bulb code, because aftermarket labeling can vary. Validate and summary: I wrote this to save you time and uncertainty, based on hands-on experience with the 2015 Audi TT. Quick recap: use the chart as a starting point, verify visually, and buy with confidence.
