Can You Put LED Bulbs in a 2012 Smart Fortwo?

Upgrading to LED is one of the most effective ways to modernize your Smart's appearance and safety profile. Since your Fortwo uses a single H7 bulb for both high and low beams, ensure your chosen LED kit is "dual-beam" compatible. This allows the LED circuitry to mimic the two-filament design of the original halogen bulb. Don't forget the H11 fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
