还有变态车大灯暗得神马都看不见,比如crv。

正确的雾灯装的低,靠近地面的雾很轻。

h**********r 发帖数: 2284 | 7 Regular headlight cannot penetrate fog effectively given it's powerful
lights reflected in all directions and may be even reflected back. A driver
can only see the very near distance with headlight on in fogs.
On the other hand, fog light is usually yellow and has lower power, which
penetrates fog better.

h**********r 发帖数: 2284 | 13 Color has anything to do with fog light. Actually, please try to find any
fog light that is not yellow, if you can. The majority of fog lights are in
yellow, which is a fact.
Following is something someone wrote in the Internet. There are debates
about it, but here's the reference as follows.
"The color of fog lights has an immense bearing as to the operation and
purpose of this type of light. When our high powered white headlights are
blasting out light energy down the highway, we are sending out red green and
blue light, because this mix of colors is what makes white light. This all
works well and good because a strong light sent down the road will net a
strong reflection from the objects your 'e trying to see, (only problem is
you probably will blind the oncoming drivers). The situation changes,
however when one encounters thick fog, suddenly the light from the nice
strong headlights lights up the fog and obscures everything in a blinding
reflection of glare. The reason this occurs is because the water droplets
that make up fog are extremely efficient at reflecting blue light, so the
blue energy component of your own headlights are reflected back at you and
give a really good view of fog. The trouble is that you would probably
prefer to see beyond the fog, so that maybe you could see the back of an 18
wheeler that you are about to crash into. This is why we have fog lights,
not because we turn them on to make the car look pretty or to make it look
like some teenager's sexy rally lights. the reason we switch off the
headlights and power up the fog lights is because the yellow filter in the
fog light passes red and green light but it stops blue light from passing
through. The blue light if you remember was the culprit, it is the light
color that doesn't penetrate fog. The green and red light are easily passed
through the yellow filter and are now the light that we are shining down the
roadway (by the way red and green light make yellow light-it's not like
mixing crayon colors) this yellow light penetrates the fog and reaches out
much farther to bounce some light energy back from whatever is out in front
of you. Well its been said, you can't have your cake and eat it too. Okay
here's the rub, since we are now sending yellow light out for illumination
we can't light up things very well that are blue in color, because there is
no blue energy in yellow light and that isn't the only problem, when we
provided the yellow filter over the fog light it killed the blue light from
getting through, about a third of the light level is killed by this
procedure. The way around this last problem is to use a bank of fog lights
to get enough light energy out there, but nothing will solve the blue
problem, because yellow light illuminating a blue sign, for instance, will
only look black. So the direction that you are shinning the light is not
what fog lights are about, it is the color characteristics of the light that
matters. "

雾里看太阳是淡白色不是黄色或红色。
如果黄色好于白色,联邦和各州早会规定用黄的了。实际上他们发现没有不同。
很多新车的雾灯是白的。
