Smart fortwo Bulb Size By Years
tl;dr: This bulb size chart lists the correct replacement bulbs for a 2015 Smart fortwo. As a technician, I made it so you can quickly confirm socket types and wattages before buying.
Recommendation: Use the exact OEM sizes listed and match headlight, turn signal, and interior bulbs. A quick checklist—verify part numbers, compare base types, and confirm voltage—saves time and returns.
Impact: Correct bulbs restore proper light output and prevent electrical issues. Wrong bulbs can cause fitment problems, blown fuses, or reduced visibility. Gotchas include aftermarket bulbs that look similar but have different bases.
Next steps: Consult the chart, check your owner’s manual, and follow the buy links if needed. Some links are affiliate; I may earn a small commission at no extra cost to you.
