BMW i3 Bulb Size By Years
Misconception: people think a bulb size chart is just a list of part numbers. Why that seems true is simple — many charts look like dry tables packed with codes. Think of it as a mental model instead: a quick map that connects what’s in your 2018 BMW i3 to the bulb type you actually need, so you avoid guessing and returns.
What is true is the chart’s purpose: to show socket types, common equivalents, and typical wattage or LED alternatives. A useful rule of thumb is to match the bulb code and socket shape, not just the wattage. The implication is less wasted time and fewer fitment surprises when replacing lights.
Quick recap and tests: check the owner’s manual, inspect the bulb code on the lamp, and compare the socket. Some links on this page are affiliate links; I may earn a small commission at no extra cost to you.
