I was wondering if someone has electrical plans or knows what relay controls the switching of the "Fog Lights & High Beams" so only one can be on at a time? I have installed HID in both and at times I would prefer to have both on along with the HID headlights I already have.

I know in my old car it was as simple as removing a pin from a relay and we had lots of light if needed.

Thanks for any responses

There's a rather long thread on this in the DIY section. There are several choices on how you might want the fog lights to operate. I think they all involve cutting a wire and splicing it to something else.

look in the D.I.Y. section for "foglight rewire". It allows you to have the fog lights on without the headlights and also to have them on WITH the high beams.

 

^both correct!

 

The rewire is for fogs with parking lights. It will also allow them to work with the high beams. I've found more use to have them work with the parking lights, but that mod does happen to work with the beams as well. (and with HID's in the fogs it's a lot of light.)

 

the HIDs make the fogs pretty useless - even without them i'm not too sure of the the fog lights fulfilling their purpose

 

^yeah I know just plain HID"s in the headlight make it hard to see in the Fog/snow/rain but fog lights are meant to help cut throgh the fog not bounce off it!

 

From his first post, it looks like Stu put the HIDs in for more light under regular driving, not for fog. So his question makes a lot of sense.

The stock fog light wiring makes them useless. If you're really in fog light conditions, you want the fogs on and the headlights off. The next use for fogs is supplemental near light when the highs are on. HID low beams (the only time the stock fogs come on) are really good in fog.

One of these days I'm going to do the mod that lets them go in independent of the headlights. There's one stretch of road that has a "headlights on" requirement, and I'd enjoy gaming it with fogs instead of heads.

I've got 3000k HID's in my fog lights and they're great for the fog. I thought they were useless before I put the HID's in.
I just wish they were aimed a bit higher.

 

Fog light mod is great. I leave mine on all the time as daytime running lights

I've tried using them in fog before but with OEM bulbs in the fog lights, the HID low beams let you see further in fog then the fog lights themselves. Might work better with brighter bulbs in them.

 

The most satisfying free mod you can do.

 

Thank You everyone for the input, this mod will work great, and solve my problem / purpose which is to put out an extremely high amount light if needed. There are some dark stretches of road and highway here in AZ, The police like to hide under the over passes etc. with this much light it makes the reflective decals glow a long way out

 

You won't see a lot of light projected onto the road. The fog lights really need to be adjusted up quite a bit to get any light out in front of you, and there's no easy way I could see to adjust them up.

 

You say that but I covered my OEM HID's to black them out before I installed the HID upgrade into my fog lights / driving lights. The before and after was quite shocking. With the lumen output and color temp change from stock things show up you normally do not see, and not only that but farther away. I accomplished this by doing one simple thing in addition to the HID's of course. I removed that pesky little metal thing inside the foglight / driving light housing

 

Oh BTW the Fog / Driving lights are 6000k and my Headlights are also 6000k I used a PIAA upgrade and changed them. About 750.00 for headlights but awesome for seeing the road (but cheaper than my surefire flashlights I have) It was an engineer who made and "off the record comment" to get more light up and out into the roadway by removing that "pesky metal thing"

 

The pesky little metal thing is to reduce glare to oncoming drivers and give a better cutoff. I guess I'll try removing mine, as I can't imagine glare would be that big of a problem with beams mounted that low. Did you break yours out or were you able to remove them non destructively?

 

Removing it was not to bad, just some patience. you have to wiggle it back and forth inside the capsule till it snaps and then use some needle nose pliers to squish it so it will fit backwards out the hole. I did not think I did to bad of job removing it. I did not scratch up the interior of the capsule as bad as I thought I would.
