Can You Put LED Bulbs in a 2004 Jeep Grand Cherokee?

For a Jeep built for the road and trail, LED upgrades provide the high-contrast lighting needed for better obstacle detection. We recommend starting your upgrade with the 9006XS LED low beams, as they see the most use. Adding a matching 9005XS LED LED kit later will complete the look and ensure consistent lighting performance. Because Jeep utilizes a CANbus system, standard LED bulbs may cause "bulb out" errors on your dashboard. Always opt for "Error-Free" or CANbus-ready kits which include the necessary resistors. Don't forget the 9145 LED fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
