LED bulbs in fogs only?
 

Yes, LED bulbs will likely put out more light, but no, it will probably not improve visibility, because the light will be scattered all over the place (i.e. it will not be focused). Furthermore, when you really need more light, you'll likely want to use your high beams, and the fog lights turn off when the high beams turn on (unless you've modded the switch). You will be far better off wiring up a set of auxiliary driving lights that can be manually switched, but wired such that they are available only when the high beams are on.

And thank you for being aware, and not being "that guy." :thumbsup:

Just wire them up to the wire that controls your brights.

You will (should) use a relay to control the lights. Follow the diagram below, using the wire that is hot when the high beams are on as your +12VDC to feed the switch. There is a wire in/from the column-mounted multi-function switch, I just can't remember the color off the top of my head.

Through a switch and a relay, yes. Directly, no. The in-cab wire is a low-current circuit. You also don't want the aux lights on with your brights all the time. Cops tend not to like them, especially when you "flash" someone oncoming when they have their brights on inadvertently. :whistling2:

Well if the wire can handle the voltage/amperage to power the brights on a halogen bulb, id assume it could add a couple of leds without issue. I wasn't talking about the switch wire in the cab...
Also I personally wouldn't wire anything directly attached to my high beams. I'd only wire them to an independent switch, not hard to switch on when you want and you have no issues of them being on when you don't.

And yeah a few states have laws that don't allow you to have 4 forward facing lights when two of them are brights.

<----- This guy was pulled over for having 6 forward facing lights just 2 or 3 weeks ago. I have them perfectly aimed too....not blinding oncoming traffic. The cop was just flexing his muscles. But hey, he didn't give me a ticket - so I am thankful for that. I think most of that was because it was a blizzard, and he wanted to get back in his Explorer though, lol.

Also, I agree... never ever ever wire lights (or other accessories for that matter) directly to the switch. They may be "rated" for it, but they should not be used for it.

I to have been pulled over a couple years for 6 forward facing lights. HID Headlights, HID Fogs, & HID Driving Lights. Never in the 3 years I had them was I ever flashed, like you said the cop was just flexing his muscles and being that I knew the law that you can have more than 4 forward facing lights on at a time it was hard to argue. Which brings me to another question, how the head does the new F250 have quad beam headlights and fogs STOCK?

OP, look into DEPO fog housings. They are factory replacements but have a clean lens. I would suggest a good 3000K Halogen bulb in them. As for headlights, look into a set of Lightning Headlights and corners. They have clear lens also. You could even go a step further and retrofit a set up HID projectors in them.

The factory headlight wiring in these trucks (well, most vehicles in general) is barely adequate at best, and I wouldn't want to add one more amp to the load. There are posts all over lighting forums about running relay setups and larger wires netting higher output form otherwise stock systems. I just haven't had the gumption to do it to mine.

Maybe because they're in one housing? Whatever the why, I DON'T LIKE THEM! those suckers are WAY too bright (as are Audi's LED's and other modern setups).
