I'm looking to purchase a 05 G35 Sedan with nav and 6mt the next month or so and was wondering why you dont see many/ANY G's with "driving" lights?

 

what driving lights? you mean the fog lights at the bottom? i believe thats the impul front bumper. the fogs are aftermarket. the 06-07 g coupes have city lights if that's what you mean.

 

USA spec G's dont have daytime running lights. I know that the Canadian Spec G sedan's use the fogs as running lights.
-GP-

 

I always thought the lights at the very bottom were "driving lights" when clear or white and are used to project further than the regular head lights when driving. If they were yellowe, then they are "fog lights". Please correct me if I'm wrong.


Thanks

 

Those are fogs, I don't know why Infiniti didn't make the OEM fogs on the G like they did for the M.

 

Thought fogs were yellow and drving lights where clear?

 

Not all fogs are yellow, yellow is just for show. Yellow does nothing to help see better in the fog. We don't have daytime running lights on American G35s. Look at fog light options on other auto websites. They go in the bumper.

 

I keep my halos on all the time so those are like my driving lights.

 

I disagree, I had Piaa yellow bulbs in my fogs before the TL projectors and they reflect a lot less light in the fog or rain. White and blue reflects more. IMO they helped quite a bit.

 

It's all in your mind.

"Your confusion about yellow fog lights is not surprising, since a lot of the
reasoning behind the selection of yellow as a fog light color had nothing to do
with physics. I've heard two reasons cited as the rationale behind the use of
yellow fog lamps: (1) yellow lamps suffer less backscatter into the eyes of the
car's driver than blue or green, allowing them to see better in the fog; (2)
yellow lamps are more readily seen by an oncoming driver, so that a car with fog
lights on will be seen more readily than white lights would be.

The first point is true for light scattered off very tiny aerosol particles in
fog -- blue light is scattered out of the path from the sun to the viewer of a
sunset, leaving white light minus blue to reach the observer... so he/she sees
yellow/red -- but is pretty irrelevant for the kind of yellow lights used for
fog lamps. Those lamps were generally made by putting yellow filters over a hot
tungsten filament incandescent lamp, so that a lot of light is lost in trying to
make the yellow light -- reducing the brightness available for the driver to
see, which is not such a good idea. Using a halogen gas fill increases the
brightness of the bulb, but the same general principle of reduced brightness
still holds. Additionally, the size of water drops in fog is generally not
appropriate for producing the kind of scattering I mentioned above -- if so,
headlights would appear very red to oncoming traffic, which they don't.

The second point, that the yellow color is more visible to oncoming traffic is
also true, but irrelevent as well. The point of fog lights is to allow the
car's driver to see better, not to be seen better -- if you wanted to be seen
better, a flashing strobe would be more effective, but you don't see much of
those in the fog light business.

Most likely, the real reason that people have used fog lamps that are yellow is
that they look so cool. Realistically, most people do not drive a lot in foggy
conditions -- certainly not enough in most cases to justify the cost of
expensive additional lights. Both my wife's SUV and my sport luxury car have
yellow fog lamps on them, but we've never used them... They came as standard
equipment on the vehicles, probably because the manufacturers thought they'd
look more bold or aggressive. Since it's more expensive to get standard package
equipment taken off a car than to just leave it alone, we've got the lights as
artifacts of somebody's idea of style.

Your observation that refraction occurs within aerosol water drops is true, but
it turns out that it's the surface scattering rather than dispersive refraction
(which refers to the fact that different colors are bent more on refraction,
leading to them being dispersed in angles) that results in the non-problem which
yellow lamps were supposed to solve. The dispersive refraction effects may lead
to rainbows being visible under certain conditions -- I think everybody's seen
them on sunny days when you spray a garden hose in a very fine mist around you
-- but I don't think I've ever looked for or seen one at night in fog or rain.
It might be fun to get a very finely misted garden hose, stand with your back to
a headlamp and your head at about lamp level, and spray a very fine mist in
front of you. You might just be able to see a rainbow at night. Fun, but not
relevent to the problem of fog lamps.

To wrap up my discussion of fog lamps, I think that the reason why folks are now
moving toward xenon arc lamps is that they're just so darned bright that they
put out tons of light which you may be able to use to see. People have realized
that it's very unlikely that you'll get so much backscattering of the light --
whatever the color -- from the aerosol water in fog that it will prevent you
from seeing something that you could see in lower light. That would require a
bizarre conspiracy of events in which the object being viewed has very low
contrast in general... which would make it unlikely that you'd see it anyway.

Thanks for your very good question... it got me thinking about stuff I haven't
considered for years!

Thats pretty interesting. All my years of driving up til just now, I have seen fogs on cars that that have always been yellow. When you see GT cars of old, the lights that projected out ahead of the old headlights where the ones that were clear/white like in the pics posted. Im just curious why I have not seen ANY sedans moded with this kind of front bumper.

 

^it would have to be custom fitted as no bumpers for sedans come integrated with the pods for fogs/driving lights.

I am looking into getting someting integrated into my Nismo bumper. I've always felt I needed something upfront like that.

 

GREAT response!!!

 

NONE? wow......I think the look is pretty nice without being ricey or complicated lines.

 

After doing a search, I'm not finding ANY sedans with fog/driving lights or ANY discussions of what I have posted here. hmmmmmmmmm
