Porsche 911 Bulb Size By Years
When I first replaced bulbs on my 2018 Porsche 911, I made a simple list to avoid guessing and extra trips to the parts store. Think of it as a compact reference showing each bulb position, size, and common replacement options so you can match what you need quickly. A quick win is finding the correct headlight or turn signal bulb number in seconds, which saves time and reduces stress.
As I expanded the list, I added fit notes for OEM vs aftermarket options and simple installation tips that helped avoid common mistakes. The mental model here is: confirm the position, check the size, choose a compatible option, then test the light. For transparency, some links on this page are affiliate links, which means I may earn a small commission at no extra cost to you; that support helps keep the chart updated. Quick recap: use the list to identify bulbs, apply the fit notes, and feel confident replacing them yourself.
