2010 Maserati Quattroporte Bulb Size

When I first needed new bulbs for my 2010 Maserati Quattroporte, I made a simple list so I wouldn't guess at sizes. Think of it as a compact reference that matches each lamp location to the correct bulb type, saving time and avoiding returns. That initial clarity felt like a small win and kept the job straightforward. As I expanded the list to include headlamps, fogs, indicators and interior lights, a mental model emerged: match base type, wattage and connector before buying. A useful rule of thumb is to compare the chart to your owner’s manual and the existing bulb.

Quick recap: use the chart to identify sizes, verify visually, then buy confidently. This approach moved me from unsure to resolved when replacing bulbs.
