those with HID's in stock fogs
looking for some info on putting hid's in the stock square fogs.
after changing to the hid bulb, is the light from the fogs still useable or does it just scatter everywhere.
some pics might be nice too. thanks!

shouldn't be too bad. With HID's projectors just aim the light and project it more efficently. your stock fogs with 3000K HID's will do all you need. But remember the light output will defiantly not be consistent with stock fog output.
My only concern with putting HID in the fog lights is that it would be too bright. If you ever drive in really heavy fog, you dont want the brightness. Even if its only 3500 temp (yellow), it would still cause a lot of glare in the fog. I just put yellow halogens in mine. It looks cool, kinda like a lexus and above all they still function as fog lights.

Here's something I found that seems to disagree with yellow being better than white for fog lights... http://www.newton.dep.anl.gov/askasc...9/phy99xx4.htm

So, our best
compromise between sensitivity for our eyes and a long wavelength for least
scattering is yellow light.

The guy is against HID lighting (which is lame, I will never go back to halogen), but other than his HID problem, he knows whats up with automotive lighting.
Yellow lamps were subjectively ranked as better in poor weather and lower in glare than white ones, and this matches my own experimental experience with fog lamps that produce yellow light...
...So, why do yellow fog lamps work better? It's because of the way the human eye interacts with different colors of light. Blue and violet are very difficult for the human optical system to process correctly. They are the shortest visible wavelengths and tend to focus in front of our eyes' retinae, rather than upon it. To demonstrate this to yourself, find a dark blue store front sign or something else that's a dark, pure blue against a dark background in the absence of white light. From any appreciable distance, it's almost impossible for your eyes to see the blue lighted object as a sharply defined form...the edges blur significantly.) Blue also is a very difficult color of light to look at if it is at all intense...it stimulates the reaction we call "glare". So, culling the blue out of the spectrum lightens the optical workload and reduces glare...

awesome, thats what im lookin for!
and your personal opinion. would you say its better with or without HIDs?
does it still keep a pretty flat beam? im sure theres a lot more glare. but as long as theres still a bright flat beam ..

Did you? Check out what the guy said:
(bold added for emphasis)
"First I'll give you the wrong explanation, which you can find here and
there. It goes something like this. As everyone knows, scattering (by
anything!) is always greater at the shortwavelength end of the visible
spectrum than at the longwavelength end. Lord Rayleigh showed this, didn't
he? Thus to obtain the greatest penentration of light through fog, you
should use the longest wavelength possible. Red is obviously unsuitable
because it is used for stop lights. So you compromise and use yellow
instead.
This explanation is flawed for more than one reason.

I used the proper replacement bulbs for the housing....believe it was 9145. Mounted the ballasts behind the grille, almost hidden. You can see it in the stright on shot, in between the bumper and grille gap.

Listen, the fogs aim. Yes, 3000k is bright when looking square at it....but fog lamps aren't ment to be aimed straight ahead now is it? It's aimed down. I drive all the time at night in the city, and have never been flashed with the fogs and heads on. I went 3000k because of the fact the 6000k and even 4300k just bounces right off snow, fog, rain.....and running just my 6000k headlamps, it really sucked in the rain.

With 6000 low means in the snow, I am better off turning my lights off completely than running 6000 in the snow.
I don't care what some egghead in front of a desk says, I have tried it and have seen the results for myself.

yeah i was already planning on 3000k, as i will be doing snow driving this coming winter. a lot of it.
just making sure the light is still useful..
and i searched it, i believe that bulb number translates to an H11 correct?

pics....photobucket is crappin' out tonight.....on the road from the driving seat pics to come.....and, as we all know, pics are hard to take of hids.
Ballasts mounted behind grille, on each lower corner...you can see then between the bumper/grille gap.
This is what happens when one is aimed up...
Driver side: 4300k head, 3000k fog
Pass. side: 6000k head, 3000k fog

+1000. The guy saying yellow is bad, have you actually had pure white and yellow? All my cars have 6000 low beams and 3000 fogs. The 6000 reflects back so much of the snow and rain it's hard to see past. With the 3000 I turn off the headlights and just use the fogs in the snow....(don't need to in rain but I can actually see in the rain with 3000 fogs and nothing with 6000 lows.

SWEET! thats EXACTLY what i needed
and you have the same exact setup that ill have.
already have 6000k headlights in.
just need some bulbs for my extra set of ballasts.
