SharpHID

Hey John,

Hope your holiday was good. I am running into a problem on the install of my 99 a6 fog lights. I have been using the blog on the audis and I have noticed that my car only has one “power” prong for the stock fog lights. When i removed the stock bulb it was just powered by one prong ,not 2.  There is another wire that comes from the same area as the one prong, but it seems like it is just attatched to a metal part on the foglight housing, is this just a ground wire? Im not quite sure how to go about this now, as the larger of the 2 prongs on your HID kit fits perfectly into that one power prong, now what to do with the second one?? I have an H3 kit which was what the osram sylvania guide on your suite told me to use , and i have bought replacement fogs before so  i know its the h3, just not to sure how to go about this. The metal around the fog housing also says h3. The bulbs that have been in there are the smaller h3, i believe they are h3c’s.. would this be a problem?  All the places i talk to say its just a h3… Any help would be appreciated.. Thanks again

I recently installed a 35W 4300K HID conversion kit on my B6 A4 1.8T Quattro with stock projection H7s. The new HIDs look excellent and well resemble other OEM Audi HIDs. The installation was straightforward. I completed it in an hour on my lunch break and experienced no ‘bulb out’ warning once everything was installed.There are however a few difficulties you may encounter and they are as follows:       -Finding all the Torx screws that hold on the headlights: There are four screws for each headlight and there is little room to loosen the lower two. On North American spec B6s (02-05) you do not have to fully remove the two lower screws, just loosen them and the headlights can slide out (the lower holes are slotted). This way you won’t drop a screw. Also, this can all be done without removing anything else… like the intake for example.        -Removing the main wire harness plug that connects to the headlight casing: This is done by pushing down on it slightly, inserting a screwdriver into the slot on the side and turning, then pulling the plug out with the screwdriver still turned. The plug should come out fairly easily once you had turned the screwdriver, so if it doesn’t, you probably haven’t turned it far enough. You could do this install without completely removing the headlights (leaving them plugged in) … but it’s nice to take them out and get a good look at them… and much easier on the hands.       -Drilling the hole in the lamp cover. In another H7 installation guide, I read to drill a 1″ diameter hole. However, the plugs you need to pass through the hole and just under 1 1/8″ across and will not fit through a 1″ hole. So use a 1 1/8″ hole saw to drill the hole and all will be well.        -Wiring: Dark to dark, light to light works great… though I don’t think it matters in an H7 anyway.  The two flat slotted male connectors go into the the female plug that pulls off the old H7 bulb. This all happens on the inside of the lamp cover. You need all the wires provided, so don’t cut anything.       -Reinstalling the headlights: I mounted the ballasts in the convenient little recess under each headlight, however this ended up causing some problems. If the ballasts are mounted in this way, the wiring has to travel out from under the headlight and up to the lamp cover. This causes spacing problems when sliding the headlights back in, as the wires interfere with the lower mounting brackets. I ended up just forcing them into place… but they definitely didn’t go in as smoothly as they came out. So maybe just rest the ballasts in the recess and try sliding the headlight in and out prior to taping them in, just to see if a similar problem is encountered. If so, simply mounting the ballasts in a different location would solve the problem.       All fairly simple stuff, but hopefully it can save you some grief. Best of luck. 

I recently purchased a 2002 Audi Allroad and it had stock reflector fogs. I had upgraded the fogs in my Volvo and loved the difference they made. The bulb type is an H7 which made the upgrade that much simpler. A full installation guide will be posted this weekend but I thought I would post up the initial results here.

I decided on the 55w kit as I wanted the fogs to be bright. There is some risk as the 55w kit gets very bright. The fogs on the Audi are of a reasonable size and being that they are H7 means they have a lot of space behind the bulb inside the fog light cap. So far I have not seen any issues with anything overheating. I do try not to let the car sit with them on for long periods of time to prevent any excessive heat. For most fog applications I would recommend the 35w upgrade.

I am completely stunned by the output of these 55w HIDs. I went with the 5000K bulbs which produces a pure white light. They complement the OEM HID low beams fairly well though I think 4300K would have matched better. They are incredibly bright and really fill in the darkness to the side of the car and directly in front. I have yet to use them in inclement weather but I have no doubt they will do the job.

Here are some pictures of the results:
