2018 Maserati Quattroporte Bulb Size

When I first needed replacement bulbs for my 2018 Maserati Quattroporte, I found scattered sources and confusing part numbers, so I created a concise bulb size chart to save time. Think of it as a single reference that lists common locations—low and high beam, turn signals, fog lamps, brake and reverse lights, and interior bulbs—paired with their typical bulb types so you can shop confidently. A quick win is matching the listed bulb type to the part in your hand before ordering; it often prevents returns. The chart expands through practical notes on polarity-sensitive LEDs and a simple rule of thumb about checking fitment for adaptive headlamps. I validated these sizes against my owner’s manual and hands-on replacements. Quick recap: use the chart as a starting guide, confirm against your vehicle, and you’ll have bulbs that fit.
