Just like the title says, is there a way to wire your fog lights so that they stay on with the high beams as well as the low beams?

I cut one of the prongs of a relay in the fuse box under the hood years ago, works well, no issues. I'll try to post back with more details, or someone else will probably pop up with it.

This info is for my car, I don't know for sure if it will work for yours. In the power distribution (fuse) box under the hood, there are five relays. According to my owners manual, relay 5 is for fog lamps. Pull out relay 5.

Look at the prongs on the relay, with prong 87 at the bottom, prong 86 to the right, prong 85 to the left, and prong 30 at the top. There is an unnumbered prong left of prong 30, this is the prong to cut. I used a Dremel and cut it flush with the base of the plastic relay.

Thanks for the help again!!

My car is also a 2002 GT so hopefully it will be the same. When you did this the fog lights stay on at all times the parking, highs, and low beams are on. Correct?

I'm out of town for the weekend and won't be able to try this until Monday but I'll let you know if it's the same.

I used method one. Easily done, fogs are on anytime your lights are (parking, low, or high beam). Best part, easy to reverse, not permanent.

Yes. And if you need to go back to stock, just get a new relay, can't be too much money.

In most states, that is illegal. That is why they make the fogs go out when you hit the high beams.

That is probably true. But offroad midpipes and many other aftermarket parts are illegal too. Oh well...

Talk about a stupid law, you cant have your high beams on when in traffic but its ok to have the fogs and lows on in traffic. How would the fogs and high beams be an issue when there are no cars in front of you.

Mine is cut off also and it doesn't work. This mod worked on my 99 but not the 03. Guess ford changed something.

On my '99, there was a "cut out relay" in the distro block under the hood that disconnected power to the fogs when you hit the high beams. It was seaperate from the relay that provided the power. I built a jumper that just connects the two pins perminantly. Now the fogs work the same as they normally did, but also with the high beams. If I want to go back, I just pull the jumper and plug the relay back in!

I have an '03 GT and used an alternate method (though the "cut the pin off the relay" method should also work OK if you have cut the proper pin). It has worked perfectly for 5 years.

The advantage of my method is you can easily restore factory operation if ever necessary, just by plugging the original relay back in.

I've described the mod in this pdf file: http://members.cox.net/n0v8or/fogs_with_hi-beams.pdf

This is identical to what 2badstangs suggested in the previous post.

Technically you can't use your fog lights on a clear dry night anyway. I was once pulled over for having the fogs on during a clear summer night.


I'm sure it's just a blanket law. It's meant for a few specific vehicles but they just apply it to every car.

Our fog lights suck anyway. I could be in a pitch black neighborhood and flip my fogs on and off and the only thing they would light up is the gravel 4 feet in front of my car.

At least upgrade to diamond clear fog lights

which cost just as much as headlamps



ok so they might not be that much. but why they have to be over 100 is beyond me.
