Check the rear third light on top they have three bulbs. When you step on the break, it illuminates, but when I checked, two were out...thus, just having one out was the cause. Also check the license plate lights they have two bulbs. One may be out. check the connections on the central bulb on the high level brake lights Some jeeps also have the side running lights (both front and rear) connected to the rear light warning. It turns out that it was a side running light that was really difficult to see it was out!!
