2009 Maserati Quattroporte Bulb Size

When I first looked up bulb sizes for my 2009 Maserati Quattroporte, it felt like decoding a small language. Think of this list as a cheat sheet I built from hands-on swaps and parts lookups; the starting point helps you identify each position and its corresponding bulb type quickly. A small win is finding the right headlight and fog lamp sizes without guessing, which usually saves a trip to the dealer. Expanding scope, I note tail, brake, interior, and side marker bulbs so you can replace matched sets and avoid uneven brightness. A rule of thumb is to check both owner manual and socket markings as a mental model for confirmation. Refining the process, I cross-checked part numbers to reduce returns. Quick recap: this chart aims to streamline replacements and reduce hassle. Disclosure: some links on the page are affiliate links, which may earn me a small commission at no extra cost to you.
