Audi A5 Bulb Size By Years
Finding the right replacement bulbs for your 2021 Audi A5 can feel confusing, especially with different sizes for headlights, turn signals, and interior lights. I created this bulb size list to solve that problem and save you time. The chart shows OEM sizes, common upgraded options, and the trade-off between brightness and heat.
Before you start, confirm your trim and headlight type; that assumption matters when choosing fitment. Use the list as a recommended reference, follow the step-by-step fit checks, and perform validation by comparing old bulbs and sockets. Constraints like CAN-bus warnings or limited clearance are noted.
I may receive a small commission if you buy through provided links, at no extra cost to you. If a bulb triggers an error or doesn’t fit, refer to the troubleshooting notes or contact me for clarification.
