How to make fog lights stay on when high beams are on

I hate when I flash my lights and my fogs flash too, and I want the fogs to be on when the high beams are on because the high beams throw almost NO light right in front of the Jeep. Is there a way to set them to be on when I turn them on, no matter what?

Charles.

From what I understand there isn't a way to make this work. I think I remember someone saying that in some states it is illegal to have other lights on when the high beams are on

There is likely a way to do this...but it is illegal to run more than 2 sets of headlights at the same time on public roads, which is why auto manufacturers rig vehicles to have the fogs cut off when the highbeams are activated

in olden times we had to wire in our own fogs with separate switch add on in the classic "drill a hole & mount something" fashion, tapping in for power somewhere.

With the complex computer bus stuff au currant, it's a step more complex.

And do check your state laws. Oregon for example has specific statute making being caught with fogs/high beams on together a $$$$ violation to do such.

What's the extra complex steps? My front facing flood lights and rear facing lights in my bumper are working fine. I just ran them directly off the battery and installed the switches inside the dash.

If it were me I would go extra extra complex and install relays too.

I don't care one iota about the law. Since there doesn't seem to be an easy way, I'll see if I can find the relay and bypass whatever causes it to turn off when the high beams are on.

It has been discussed ad nauseum previously. A search should give you some ideas.

I never could figure out this law. If you have high beams on obviously there is no one coming the other way so why does it matter ?

Because we've all run into jerks who run their high beams and refuse to turn them off for oncoming traffic I suppose

Seems to me that the fog lights are for bad weather...I.e. snow / fog and the light is to show the way home directly in front of you...I agree that true fog lights should be amber, to cut through the "junk", so I am wondering why they weren't made properly in the first place.

This feature is actually for your safety. Having both lights on, dogs and high beams will make your eyes adjust improperly and allow too much light in making it harder to see further down the road. Thus making your highbeams pointless.

I've thrown this out before in a different thread but in my other car all that is required is you bend/break off one of the tabs on the fog light relay thing.

As you can tell I'm not too electrically inclined so I havent tried to figure it out on the jk yet. But if there is a relay (or whatever it's called) for fog lights I bet there can be a similar solution.

one just needs to install a relay so the fogs still receive power once the high beams are on. Simple fix.

I have my set to turn on with the high beams through my Bully Dog GT. it's a feature that I really like it makes a big difference.
