Can You Put LED Bulbs in a 2019 Smart Fortwo?
Upgrading to LED is one of the most effective ways to modernize your Smart's appearance and safety profile. We recommend starting your upgrade with the H4 low beams, as they see the most use. Adding a matching LED kit later will complete the look and ensure consistent lighting performance. Don't forget the H16 fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
