Fog Lights only on with out head lights?
 

Any body done this?
Do a rewire to have only the fog lights on without the head lights having to be on?

There's an "always on" module you can buy that's plug-n-play by Diode Dynamics.

IIRC, that's for the boomerangs not the fog lights.

Oh ok thanks for the correction.

Carista able to do that?

i recently just had a really good experience with a lighting guy on here. his name is HeresMyMind. i bought a set of second hand yellow fog lights from him and after talking to him for a while i found out he does a lot of custom work and wiring/retrofitting, etc. you could reach out to him and he might have a solution for you.

You will need a dedicated switched 12v source so lights will get power only when car is running. You could also buy fog light wiring kit and run it separate from the OEM wiring.

It comes standard with GT86 models in Australia

So then it's probably a matter of the right relay part number...

This idea keeps coming back... check out the older threads. The important question, rather than how, is... WHY?!?!?

Headlights make it worse. Foglights make it better. I would love to drive with just the leds and the fogs when it's misty.

If it's misty, you've got your wipers on. If your wipers are on, you've got your headlights on (at least in my state). Then.. foglights. I can't think of a situation where I'd like my fog lights on but NOT my lo-beams. Hi-beams definitely make things worse, but low beams plus fogs are a winning combination unless you're doing 5 mph. Just my opinion.. and the law where I live.

Yeah CT law says headlights on even if it's overcast but the intent behind the law is visibilty. You can be seen just fine without your HIDs.

Point taken... but try arguing with the FAA about the "intent" behind article 14, part 117. Plus, and in my mind way more importantly, I can see better with my lo-beams and fog-lights on simultaneously. Properly mounted and aimed fog lights help illuminate the lane/road edges/sides and immediate forward path.. say, half a second or so unless you are crawling forward at walking speed... the lo-beams take care of the next second or two forward. Perfect combo. Sure, I could put a rotating beacon on my roof and be seen, but so what.. that hardly matters if I can't see what's in front of me in fog and drive off the road.



No?

There's been times where it seemed better to have just the running lights for me, but we get some thick shit in CT.

The absolute WORST pea-soup fog I've ever seen was down on the Outer Banks in North Carolina, between 4:30am - 6:00am. I could barely see the front of my car, much less more than a few feet of road. Not fun.



WAY off topic.. was at my home base airport a few days ago, and a guy had just come in from Long Island in a small twin... had wing boots, but still he left PILES of 1" thick ice on the tarmac after flying in. I didn't sleep that night, just thinking about it. You professional dudes have my respect; ice scares the crap outta me.

He probably didn't sleep that night either. I only fly the club planes VFR in the winter unless it's abnormally warm. At work, in the PC12 we have boots, which are OK as long as the icing is only moderate. They fail though sometimes probably more often than any other system (usually only little section but still). The CJ3 we have heated wings... knock on wood but I have yet to see ice that can beat them. You turn those bad boys on and within 5 seconds the ice just shears off the wing. They also almost never fail because it's just hot bleed air heating a metal leading edge instead of some balloon thing that has to inflate and deflate. The $10 million dollar jets I get to play with at work certainly have some little advantages over the $100k piston singles that I can afford to fly for fun.

Unless some company created a relay or something similar for this purpose, then you cannot accomplish this with the factory wiring. You'd have to install an on/off switch along with custom wiring so you can control when you want the fog lights on. With that said, its not that hard to do, almost every fog light install guide on this forum is done via custom wiring/wiring harness.

it's really not that hard to do with the majority of the factory wiring either. all the relay needs is an alternative power signal.
