And now I know why the "old fashioned" fog lights were yellow:
Are yellow fog lights really better than white or blue ones?
The old wives' tale that yellow fog lights give you greater visibility over white or blue ones is just not true. The premise of that superstition, that yellow light waves are long enough to pass through water particles without reflecting back into the driver's eyes, is based on a misinterpretation of Lord Rayleigh's principle of light scattering. As it turns out, the water particles in fog and mist are entirely too large to have an effect on any light waves from fog lights, be they yellow, white, blue or even green. In other words, any fog light that is properly mounted and aimed is effective, so don't worry about the color.
AND........
Where do I mount my auxiliary lights?
Fog lights should be mounted low on your bumper because they work best when they are close to the ground. The recommended mounting height is between 10" and 14" off the ground. Most vehicles have openings in the front valance specifically for fog lights.
Driving lights are usually mounted higher so that they can be inline with your headlights. Generally, they should be installed between 14" and 30" off the ground, depending on your vehicle. Driving lights can be mounted almost anywhere on your vehicle. Some of the most common spots are on top of the bumper, on grille guards, on billet grilles, on roof-mounted light bars, on roll cages and even on roof racks. Check with your local laws before you mount them because many states have a height restriction on lights for street use.
These are sort of "driving lights" so easy to get them 14 -30" off the ground on top of the bumper........if we drill them.
