Decision: this bulb size chart exists to help you quickly identify the correct replacement bulbs for a 2020 Mazda MX-5 Miata, reducing guesswork and wasted purchases. Constraints include variations by trim and aftermarket options, so the list focuses on factory-equivalent sizes and common swaps; the options presented reflect standard halogen, LED, and HID types. Comparison-driven notes highlight differences in brightness, fitment, and thermal considerations, offering an evidence-based interpretation that supports a practical recommendation: match socket type first, then consider LED upgrades only when thermal management is confirmed.
