Can You Put LED Bulbs in a 2005 Cadillac Escalade EXT?

Upgrading to LED is one of the most effective ways to modernize your Cadillac's appearance and safety profile. We recommend starting your upgrade with the 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 880 fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
