There are bulbs/LED lights out there that arent compatible with our system. When i say not compatible i mean that even though they work, they trigger the "lights out" indicator on the dash. I have come to learn that we have a Canbus system. Although that may only pertain to the headlamps. However, i put LED lights in place of my license plate bulbs and even tho they work perfectly fine, they trigger the "lights out" light on dash. I will also add that no matter what make, model or style light bulbs i use, i have NEVER owned a car that damn near has some light out on it every month. The one and only part that was handled by Chrysler and they couldnt even get that right
