I think the first thing you should do is Research!!! All of us here know what we wanted, and chose a light to try and get that accomplished. By research I mean the purpose of each bulb style, the lens that the bulb sits behind and the housing that houses it all. Everything will make a difference. "fog" lights have bee around since the 30's as options and aftermarket. Cars had only been around a bit. Originally you had to get out and use a match to light them! By the 30's not many if any were even "sealed" beams. Look at any pictures and they were all mounted very high on the vehicles. This was FABULOUS for the day. A 'fog" light was added - back then all were amber and mounted much lower usually at bumper level. They were, again, a big improvement! That term has stuck around a long time!!! In todays lighting 'Fog" lights are not that great. The beam of light leaving the assembly is, of course, modern bulbs. The beam however can almost blind the operator in actual fog. Most are a 30-35 degree beam. That means the light leaves the housing and goes - right, left, up, and down that many degrees. AND THAT is up into the fog, snow, sleet, or rain. Go out on a real foggy day and hit your high beams you will see less than with your lows. I called, talked to, and looked up lots of "stuff" about vehicle lighting. As a result have change almost all the lighting on our vehicles (cars, trucks, & motorcycles).I chose to get "driving" lights and mount them as low as possible. Also got a set that I could adjust the beam up, down, right, or left. Most driving lights only have a 6-8 degree beam. My lights lenses are just 17.5 inches off the road. Sometimes company's use the term wide for a "fog" type beam & narrow for a "driving light beam. I went to "Diode Dynamics" Got a set of there 6inch light bar aux. light kits item/part no. R110925 ( they also make same light in a wide/fog beam). Measured output 1400 lumens & 6000K color for either one. BUT!!!! the difference in what they light is amazing. Wide/fog 230 meters - Narrow/Driving 470 meters. Same bulb just different lens & housing internals. On my 16 Tradesman they mount in the open part of the bumper near the plate. Lots of info on line about them. They come with lamp assemblies, wiring harness, mounting bracket, and a package of "stuff" to universally mount where you want. Worth a look see, if nothing else how easy they are to mount. Lots of videos. They did what I wanted and since mounting have only gotten two vehicles to flash at me.
PS; I have never done anything with my vehicle standard lighting, Personally I believe they are to high off the ground to get the results I am after. I want to light the road/path I am taking, not the sky around me.
