I have the pre-facelift A4, so the foglights are built into the headlight housings.

So, if I were to get these headlights, would the foglight switch become completely useless?

EDIT: Forgot to put the damn link in here. http://cgi.ebay.com/ebaymotors/ws/eB...m=360099024205

I wonder what would turn the halos on...

Can someone point me to a good pre-facelift to post-facelift foglight mod thread?

Anybody with a pre-facelift A4 ever used these kinds of aftermarket lights and figured out how to add fogs?

 

the parking lights turn into the halos.. so 1 click on the light switch

 

Hey JC...

Then the foglights switch becomes useless? Can I tap into the wiring and add POST-facelift fogs?

 

idk i have a post facelift.. there are these little bulbs i have in my lights that do nothing for me, those might be the fogs.

 

Yeah u can tap the foglight wire on your harness, im not sure if the post ones draw more current, if they do you could add a relay, if not you can wire direct. Use a multimeter i cant remeber which wire it is.

 

Cool...I'd like to keep the fog lights...but I gotta find out how to fit some post-facelift ones on my car.

 

Very easy to do. The green/yellow wire in the headlight harness is the fog wire. There is no difference in current draw between pre- and post-facelift fogs - both are H7 bulbs. Use a wiretap to tap into the fog wire, run the wire down to the new fog, and ground the new fog in the engine bay or on the brown wire in the headlight harness. My car is a pre-facelift and I'm using facelift fogs plus depo projector lights. It works as if it left the factory this way.

 

So, what are the differences between the lights I posted a link to at the beginning of this thread and the Depo lights you're talking about?

You told someone else on here where you got yours on ebay, and I looked for them, but it seems the seller doesn't carry them anymore.

 

Well for starters, the lights on Devil's car are two piece "S4" lights, not one-piece halos like yours, so there was no trimming involved in his, whereas you'll most likely have to trim your inner fenders to get them to fit.

I haven't looked for headlights in a while, but if you check ebay occasionally that kinda stuff will show up for a few days, and you pretty much have to jump on it.

 

and just so you know, those lights should be a perfect fit. i bought lights for my car and they had the prefacelift connectors on it. i had to make a custom connector so its not perminant
