I surched and couldn't find a definate answer.

On my 03 I only had to bend out one of the relay pins, please tell it is that easy.....probably not

 

Could you explain when just out of curiosity I make no judgement I just would like to know what circumstance while driving would make you want fog and High Beams on?

 

The first thing I thought of when I read the question is why. Why do you want your headlight on with the fog lights?

Having your headlights on with your fog lights is the worst thing you can do

It defeats the whole purpose of having fog lights. I was ticked off because my Lexus fog lights would only work with the headlights on. I am glad that Dodge did it right

Fog lights are meant to be low to the ground. if you are in a fog turning on the headlights will not help because the fog will just absorb and refract the light. The point of fog lights is to have the area below the fog layer lit. Usually in most fog areas there is a few inched of fog free area near the ground and that is where the lights will be most effective.

It is hard to explain so I copied this article

From this web site

Dear Tom and Ray:


Do fog lights work? Do they help you see through the fog, or do they just light up the fog? Are yellow fog lights better than clear fog lights? Should they be mounted low on the vehicle to search forth underneath the fog cloud? I am so confused -- you might even say I am "foggy" on the fog-light issue. Therefore, I ask you to search through the fog of your collective brain cells and enlighten the world to the truth about fog lights. -- Pat

Ray: Great question, Pat. How I wish this were the only subject we were foggy on!

Tom: There are many different kinds of lights that people put on the front of their cars these days. There are driving lights, fog lights, Velux motorized sky lights ... we've seen 'em all. Most of them are purely decorative. And many are used and/or aimed incorrectly, and they simply blind oncoming drivers.

Ray: But fog lights, when used and aimed correctly, might be useful to some drivers. As you probably know, if you project light directly into the fog, it bounces off the fog droplets and reflects in all directions, making it even harder to see. That's why you use your low beams in fog rather than your high beams.

Tom: Fog lights are low-mounted lights (bumper level or below) that project light that's cut off at the top. So the light pattern on a good-quality fog light goes straight out at bumper level and down, but not higher than that.

Ray: The reason for this is that fog tends to hover about 12 to 18 inches off the ground. So by projecting light in that fog-free pocket, you can illuminate the road a greater distance from your car and therefore see farther ahead. Some people swear by fog lights. Others claim that they don't really make much difference.

Tom: So the question becomes, to yellow or not to yellow? There's a lot of debate about this, but the research says that yellow lights are no better than white lights at penetrating fog. The theory bandied about was that yellow light has a longer wavelength and is therefore less likely to be reflected by the fog particles. Turns out, this is complete poppycock.

Ray: Apparently, the fog particles themselves are so big that they reflect all colors of light. Basically, all light bounces off of them, so using yellow light instead of white light gives you no advantage.

Tom: Plus, in order to get yellow light, what fog-light manufacturers do is put a yellow lens over a white light. That cuts your light output by 20 percent to 30 percent, which is counterproductive.

Ray: So if you live in a coastal area where fog is a real problem and you want to give fog lights a try, we'd suggest a set of high-quality, white fog lights that are professionally mounted to be sure they're aimed correctly. And don't forget to check their aim periodically. Since they're mounted low, they can be knocked out of alignment when you run over things like snow banks and stalled Toyotas.

Becouse I use them on the highway in the country. Ever spotted a deer in a ditch next to the highway or country road in the middle of the night? If not, it's becouse you couldn't see it until it jumped out in front of you. Fog lights help you watch the ditches.

If you are ever on a deserted country road, turn your fogs off and on and see what a difference it makes.

The more light the better.

I could care less about the FOG.

 

I assumed that fog lights were used to see in fog, now that I know why you want to use them with the headlights I like the idea and may try they idea myself.

I just walked out to the truck to see how the fog lights worked but couldn't figure out how to turn them on (with or without the headlights). I am going to have to read the owners manual to figure out how the fog lights turn on.

 

Push the headlight dial to turn them on.

 

Mine has a separate little button for the fog lights right under the headlight switch just a small little guy

 

As previously posted.Mine are push buttoned, Another tid bit of info that was not addressed in some states it is actually illegal too run fogs' with your highbeams. In good ol' Ct. it is on the books. I've been pinched in the past with aftermarkets.btw.
They call it over illumination. They also give inspection stickers on the led lights above the headlamps. The ones mounted on the hood for example.

 

Thanks I got back outside and try it. I have only had the truck for 18 days and haven't even driven it at night yet, it has less than 200 miles on it.

This is the first vehicle I have owned without and owners book to look things up, I got an owners DVD and it is nice that the DVD has videos but it would be nice to have a book to keep in the truck

 

Thats were my cargo light switch is. Are you sure its for your fog lights?
