BMW 320 Bulb Size By Years
Goal: this bulb size chart helps you avoid buying the wrong replacement bulbs for a 2018 BMW 320i. Many owners struggle with mixed OEM and aftermarket sizes, so the chart lists the recommended bulb types and common alternates to reduce guesswork.
Prerequisites and step by step: verify your vehicle model year, inspect the bulb sockets, and match the chart codes to the parts. I recommend confirming part numbers in your owner’s manual or on the lamp housing. Validation: test-fit before installation and check beam pattern and brightness to respect legal constraints.
Troubleshooting and wrap up: if a bulb doesn’t seat properly, re-check socket type and wiring. Note: some links on this page are affiliate links; I may earn a small commission at no extra cost to you. This helps maintain the guide while keeping recommendations practical and trusted.
