Audi Vehicle Bulb Guide
Find the Correct Bulbs for Your Audi
Use this guide to identify the most common headlight, fog light, parking light, brake light, reverse light, indicator, and interior bulbs used in popular Audi vehicles. Always verify your bulb type before purchasing, as specifications may vary by year, trim level, and market. Many newer Audi models are factory-fitted with full LED or Matrix LED headlights — always confirm before ordering.
