Audi A4 Bulb Size By Years
Decision: This page presents a concise bulb size chart for a 2020 Audi A4, intended to help you identify correct replacement bulbs quickly and reduce trial-and-error. As an observer_analyst with hands-on experience, I focus on evidence and interpretation from manufacturer fitment and common aftermarket options, noting limitations where compatibility can vary by trim.
Options: The list compares halogen, LED, and HID possibilities for each socket, explaining typical differences in brightness, heat, and lifespan. The comparison highlights trade-offs and a practical recommendation: match OEM specifications first, then consider reputable LED upgrades that meet CANbus and heat-dissipation requirements.
Recommendation and risks: Use the chart to source bulbs but verify fitment against your vehicle before purchase; wrong bulbs can affect beam pattern, electronics, or safety.
