I have a 2004 LJ Unlimited with the factory fog/off road lights or whatever they are called. Saw another TJ in town that was likely a Sahara model (green w/tan top) that had the same lights on the bumper as mine. Got me thinking about how many years Jeep put these same lights on. Is it only the 2004-06 models? I'm new to Wranglers and cannot identify years of production by looking at the bumpers, if that is even possible. Like others, once you buy a particular model you tend to notice them a lot more. I live in a mountain community and there are LOTS of Wranglers and the newer four door models here. I was usually noticing pickups like mine. Of course maybe I am just not observant.
