I'm thinking of getting a pair of vintage style bumper mounted fog lights for my 66 P-100. I want these for fog and snow, not so I can blind oncoming traffic or go bajaing! Question is, what are the pros and cons of yellow versus clear lights? John

 

I am assuming the yellow lights have less glare in the fog or snow. Probably similar to the yellow tinted sunglasses you can get that people wear at night. That's just my uneducated guess, I googled "yellow versus white foglights and I got a lot of hits.

 

Thanks for the search idea/lead/ I didn't think in those terms. It sounds like yellow is a better choice, now I just need to decide who to buy from. I think I'll stay away from LED's though, from experience with warning lights on plow trucks and talking to truck drivers, they don't generate enough heat to keep the snow off them. John

 

I have heard the highway departments up north have that same problem with LED traffic lights.

 

I have spent a lot of time trying to find the best for color and have found that the amber is better than the white. We found the 'blue' tinged clear bulbs to be best at cutting through the fog, but they are not DOT legal - turned out they are an aircraft landing light. The LED's do work good, mostly because the can separate the light colors by spectrum and utilize the blue light to cut through the moisture particles, the problem being as you state they do not get hot enough to melt the snow off. The biggest thing that was found is the light pattern (beam) that the light gives off. There are several beams to choose from such as flood - close up dispersed lighting, driving - narrow long distance lighting and so forth. As I remember there are 4 different distinctive lighting patterns, so try to find the one that works best in your situation.
Not trying to give you too much info - just letting you know there are options out there after you pick the color.
My experience was gained from plow trucks from the inner city to the wide open expanses and mountains.
Hope this helps.

 

Thanks for the info. Last night was the first time I drove it in the dark and sitting almost 4' above the headlights and they are about a foot lower than on my old Express van sure makes a difference. The headlights may be low enough to work, I guess I'll find out soon enough. I may get a set of yellow fog lights and mount on the bumper just for the "cool" look. John

 

Above the headlights? That would not be legal in my state for use on the road. If they were above the headlights I would have to run covers on them for on road use.

 

No, the fog lamps would be slightly below the headlamps. But the headlamps are lower in relation to eyelevel than normal, kind of like a Cabover. I'm thinking that may make the difference, I guess I'll find out in a few weeks.
