Hi guy!

Quick question... Is there a way to keep my fog lights on while my high beam is on? I have a 09 G37x 7AT if that matters.

Thanks

 

Not normally. You can modify it to have fogs on while hi beams are on, but it involves cutting into your wires which a lot of people shy away from. I haven't done it on my car, but I know how if you want to try it yourself.

 

Yes i'm very much interested
I am planning to put 55w hid on my fog lights as well, but I still want to be able to turn off my fog lights with the stock switch.
I was thinking of getting a HID relay and connect the remote to the current fog lights and and connect the power to head lights, but I wasnt sure if that will be sufficient of power for a 55w ballast and the 35w stock head light ballast.

 

May I ask why you want to do this when high beams and fog lights are designed to be on in exact opposite road conditions?

Just wondering?

 

you can hook up the 55w ballasts to your fogs with a relay and still use your stock switch with no problem.

that has nothing to do with your high beams and fogs alternating though.

 

I'm with TTZ2G in that it's kind of ssilly to wire fogs to work with hi beams - there's a reason why no cars come wired for them to work at the same time. But since you are putting in 55 watt fogs anyway, I doubt you are really using them as actual fog lights. Like a lot of folks here on the forum I presume you are putting some whiter brighter bulbs in that space that will not illuminate the road in the fog at all, correct? You will only end up doubly blinding oncoming traffic and I think it's a bad idea.

I will reiterate that I have NOT done this on my car (there's no way I'd do this to my G), but I have done it on other people's cars in the past successfully and the principle is the same. PROCEED AT YOUR OWN RISK FROM THIS POINT. Now that I've gotten my disclaimer out of the way, here's the basics of how to wire the fogs to work with the parking lights, low beams, and hi beams.

1) Locate the fog light relay (I don't know where it is on the G37 because I haven't looked - consult the FSM). Cut the +12v wire.
2) Splice a long piece of wire into the side running into the relay. Tape off the free end of the +12v relay wire you just cut.
3) Test before proceeding by touching the free end of the long wire you spliced into the relay to the positive battery terminal while your lights are on. When switched on, the fogs should remain illuminated whether the car has on the parking lights, low beams, or hi beams; check each one.
4) Run the wire to one of the parking lights and splice it into the +12v side of the parking light.
5) Done.

 

if your using high beams, its to see further down the road. fog lights will light up like the first 15 feet. seems pointless to do.

 

Am I understanding this right?
1. find the relay and cut the +12v of the relay on the battery end.
2. Splice the +12v of the relay on the relay side. Tape off the free end that runs into the +12v.
3. Test it
4. Connect the spliced wire to the parking +12v

I want to do this because I want more control over the fog lights. I will keep it off most of the time when I drive, but when I drive in the county roads I need the lights on. I live in Minnesota, where you have to spot deers on the road. These fog lights will help me to do so. My intentions is not to blind people on the road.

 

You got it. I have no idea if this is legal or not, I know cars aren't manufactured to allow fogs and hi beams together and that's for a practical reason. Post how it turns out.

 

To me this doesnt make sense. Are you telling me that I have to disconnect the relay's +12v from the battery and then hook it up to the parking lights +12v. To me that is just changing the +12v cable.
