2020 Hyundai Ioniq Plug-In Hybrid Bulb Size

Decision: provide a concise bulb size chart and practical guidance for a 2020 Hyundai Ioniq, so a reader can identify correct replacement bulbs quickly and confidently. Constraints include model-year specificity and common aftermarket variations that affect fit, brightness, and voltage compatibility. Options are listed by socket type and typical applications — for example, headlight, fog, turn signal, and interior bulbs — and compared by longevity, lumen output, and heat generation. Interpretation of those differences helps form a hypothesis about which option balances performance and cost for typical driving conditions. Recommendation is to use the chart as a primary reference, cross-check part numbers, and prefer reputable OEM-equivalent or well-reviewed aftermarket bulbs. Risks include incorrect fitment or electrical issues if installation deviates from specifications.
