2018 Ford Mustang Bulb Size

I started this bulb size chart because I once wasted an afternoon guessing which bulbs fit my 2018 Ford Mustang, so think of it as a simple roadmap from frustration to a quick win. My mental model is basic: match the socket type and the location — low beam, high beam, turn signal — and you’re most of the way there. That small win feels like replacing a bulb in under fifteen minutes. From there I expanded the chart to show common replacements, typical lumen ranges, and points to check for fit and polarity. A helpful rule of thumb is to cross‑check the chart with your owner's manual or the existing bulb markings before buying. I refined the list through hands‑on swaps and by noting where common mistakes happen. For validation, I’ve included links to products I’ve used so you can compare options. Quick recap: this chart is meant to guide, not replace direct inspection. Some links are affiliate links, and I may earn a commission at no extra cost to you.
