I want to wire my front fogs on a desperate switch, that's the easy bit. But when they are off I want them to come on with main beams. What is the legality of this? And, how is it done?

 

Thanks, Dan

:lol::lol: sorry mate just found this funny

Lol dam iphone!!

I think it's called a chav switch... fogs on at same time as low beam... :D

 

the DVLA has information about this, it's a little fuzzy on exactly what you can ans can't do as far as extra lighting... (i don't know about the switching)

 

 

but if you have lights that can be seen as a hindrance or interfere with other road users ability to see the road clearly the police can book you for it.

Go and have a look on the DVLA site and make up your own mind.

It may well be called a chav switch but in narrow country lanes at night they help to locate the edge of the road nicely particularly when a 4x4 has it's HID lights blinding you :)

Ah, I see... yes you are correct.. I have been in that situation a few times... :)

surley why would you want a seperate switch cas if was fogy then surely you would hace your dipped beam on as well wont you, dame im cofused again.

As Bob says the fogs do light up the sides of the road very well and I'd never be without mine, especially when they are converted to HID lights.

 

You must always have separate control though IMO, but if you insist you need to wire two positive lines to them, one from your switch and the other a take off from your low or dipped beam, a load of messing if you ask me - just have a switch you hit when you want them on and hit again for off - simples.

Cheers guys but I think theres some confusion-If my fogs come on with my main beams they wont dazzle anybody though as I never drive towards anyone with my main beams on...

 

Can anyone help with how I can wire this setup?

Your fogs will come on with your dipped beams mate not just main.

This is something I found from another forum, can any auto electricians confirm this will work for me? Thanks

 

Yes that will work but it's showing main beam and not dipped, you decide which you want your fogs to come on with and have this wire sent to position 85 and when you trigger, the relay will energize between 30 and 87, thus giving power to your fogs :cool3:.

To add another factor in regarding the legality of what can or cannot illuminate with main beams.....

 

There are 2 generally accepted "types" of auxiliary front lights - fog lamps and driving lamps.

 

Fog lamps are exactly what they say on the tin - additional lights for use in restricted vision. Fog lamps are designed to shine a beam downwards "under" the fog so as not to reflect back off the fog, thus impeding the driver's vision. Fog lamps should illuminate with either side lights or (more usually) dipped headlights. Whether or not they extinguish when you switch to main beam is (I believe) optional.

 

On the Vauxhalls I owned in the 1980s and 1990s, the fogs (OEM fitment) went out when I switched to main beam - after all, main beam is useless in fog as you just get a thick white cloud reflected back at you!! On the newer cars (certainly the Mercs) I have owned more recently, the front fogs remain on when I switch to main beam....

 

Driving lamps are additional lights to supplement the main beams only - think rally cars; or on the road, the Ford RS Turbo, XR3i and XR2 of the 1980s. Driving lamps may be in the same position on the car as fog lamps, but they do not shine downwards - they aim ahead to light up more of the road. Hence they can only be used with main beam and not operate separately.... Which is why on some modern (especially German) cars, there are integrated driving lights inside the head lamps. I have them on the SLK - it has Bi-Xenon headlamps; where the HID projector functions for both dipped and main beam (the HID part "shifts" upwards when switching to main); but there are also a pair of halogen H7 lamps which come on in addition to the xenons when switching to main. And when "flashing" the headlamps with the dipped beam off, only the halogen driving lights operate....

 

So there should be nothing to stop you wiring up your fog lamps to operate with your main beam - I am not so sure as to whether you could still use them as "fog" lamps on their own as well though.....
