I had the ones that are a little smaller than the ones that are shown in the photo above (I think 3.5 inch diameter). I had them on the Jeep for one day and I didn't think they were very bright, so I took them off. I put Rigid Industries LED lights on instead. I think the problem with the Warns was that they were wide beam 'fog' style, and I mounted them on my windshield pillars, so it was partially my fault because I was asking the Warn 'fog' lights to do the work of 'pencil' beams.
The Warns were very well made, and the wireless remote was nice. The round housings looked pretty cool because they matched the round factory lights on the the Jeep (my only complaint with the Rigid lights is that they are square, I got over that as soon as I saw how bright they were though). The Warns would make a pretty good bumper mounted 'fog' light for everyday (night) driving, but not a windshield mounted light like I attempted to do. I only use my windshield lights off-road to my secret hunting/fishing spots. -Todd
