2019 BMW X3 Bulb Size

Decision: provide a concise bulb size chart for a 2019 BMW X3 so a skeptical reader can identify the correct replacement lamps quickly and avoid mismatches. Constraints include variations across trims, optional lighting packages, and the limits of an online list compared with physical inspection. Options: the chart compares common lamp types — low/high beam, fog, turn, tail, reverse, and interior bulbs — showing OEM size designations and common aftermarket equivalents. Evidence from parts catalogs and manufacturer specifications informs the interpretation, while acknowledging the limitation that some vehicles may differ by factory options. Recommendation and risks: use the chart as a starting point, cross-check the vehicle’s owner manual or the bulb itself before purchase, and consider socket fit and wattage.
