2018 Volvo S90 Bulb Size

Starting point: I made this bulb size chart because I once fumbled through replacing lights on my 2018 Volvo S90 and wished for a single reliable reference. Think of it as a compact mental model that lists common bulb types and where they fit, so you can find the right part without guessing or buying extras. Small win: I focused on the most frequent replacements first — headlights, fogs, turn signals — which are usually the ones that matter most for safety. The rule of thumb I learned is to match the bulb code and check fitment against your car year and trim before purchase. Expand and refine: I tested the chart by actually swapping bulbs on my S90 and updated sizes where fitment felt tight. Quick recap: the chart helps you pick parts confidently.
