Can You Put LED Bulbs in a 2018 Subaru Legacy?
Upgrading to LED is one of the most effective ways to modernize your Subaru's appearance and safety profile. We recommend starting your upgrade with the H11 LED low beams, as they see the most use. Adding a matching 9005 LED LED kit later will complete the look and ensure consistent lighting performance. Don't forget the LED Fog Light fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
