Awesome information 5-90 and fantic!

As stated, we learn something new every day. I have always wondered why some refer to white lights as fog lights when I have always believed that the purpose of fog lights was to cut down on the refraction by using yellow. I think a lot of people don't really understand the true purpose and differences between the two colors and how they have different applications just as the differences in the light beams themselves have different applications and purposes. I think the two of you have really shed some light (pun intended) on this subject.

Thanks!

Once upon a time, I heard that fog lights were yellow because the perception was that London has lots of fog, and old oil fired lanterns on horse drawn carriages put off a yellow light. Obviously, the thinking was, if yellow light is good for the London fog, then yellow/amber MUST be far superior to white light.

Now to my own conclusions. I had both amber and white fogs on a car I owned a lifetime ago. In fog, or dust, or almost every other situation, I couldn't tell a significant difference. But I can tell the difference with beam patterns these days. Far more important to me than light color...

hmmm I always thought fog lights put out a really wide beam of light... more like ambient lighting instead of focused light that just bounces back blinding the driver.

eh

Be sure to put a fuse on the hot wire to the lights. That way if it gets to hot to melt something the fuse will blow before and wires start to melt. Use a 30amp fuse.
