I dont have the lights. I will be replacing the bumper with an ARB one soon and will put driving lights on instead (something I will get much more use out of). Plus I rarely drive at night in fog anyway.
Also, it is my understanding that fog lights are intended to help light up the road at night when in fog by projecting light as close to the road as possible where the fog density is at its lowest. I find that most 4wds/suvs have fog lights mounted too high for them to be of any real value, instead they often make visibilty worse with the increased reflection. I have driven sports cars and sedans with fog lights that are only 4-6 inches off the road and its amazing how far the light travells down there, definately worth it then. But I have also heard that the lights increase your visibilty to other drivers too, so each to there own.
