Can You Put LED Bulbs in a 2003 Saturn LW300?
Upgrading to LED is one of the most effective ways to modernize your Saturn's appearance and safety profile. We recommend starting your upgrade with the H11 low beams, as they see the most use. Adding a matching 9005 LED kit later will complete the look and ensure consistent lighting performance. Don't forget the 899 fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
