So is using fog lights as driving lights they are two completely different kind of lights. Folks tend to forget this and use the fog lights as additional driving lights. I stuck 50w HIDs in my fog lights because I use them as fog lights their intended purpose (the same way as if I was driving with high beams). All fog lights have a very wide beam pattern. Driving lights are narrow so they don't shine in other drivers eyes.
I must be misunderstanding your post here. Fog lights are supposed to shine their light low (and wide) just like low beams, but lower since they're mounted lower, to get below any fog.
Aimed correctly they can't really blind anyone...if they are proper fog lights, which the OE Ram ones really aren't, based on their miserable light pattern.

That's one reason why the fog lights only stay on with the low beams, since they shouldn't blind anyone.

Driving lights are like high beams and will definitely blind people, which is why they must go off with the high beams.

Most folks trucks sit to high and a lot of cars sit to low. While ideally they should have a great vertical cut off in practice they don't. Because they are wide and you truck sits higher in the air that wide beam ends up hitting oncoming drivers right in the face. This is why I said instead of standing in front of your truck stand off to the side. If you stand in front of your truck everything looks fine. If you stand off to the side at car (human eyes sitting in a seat) height you get blasted and usually at the last second as they pass you.

Driving lights project forward instead of off to the side you can aim them just like low beams and keep the light from traveling into the oncoming lane. (if you try and project driving lights out far their beam can go wide. But that's the same with low beams.) If you get a correctly designed driving light you can keep the beam in your lane.

The only people getting blasted by properly aimed fog lights, even on (my) truck, would be someone zipping around on a go cart. Given i am using he nice sharp cut off line of the Morimoto fogs, but lights should be aimed level with their starting height, or slightly downward. So to be blasted by that light, you need to be at that height. Might someone disagree with my low beams? maybe. but they would disagree with them regardless of what bulb is in them. Being projectors they are aimed correctly (note low beam should definitely be aimed slightly down, i forget the spec, but i know when i aimed them i had it in one hand and a tape measure in the other)

But like JImmy said, the factory fogs are a joke for fog lights. Upgrading the lights in them would probably piss people off, that's why i said to pay attention to your beam pattern, putting in aftermarket bulbs into reflector housings can have drastic differences for the beam pattern, and can easily blind drivers. Couple that with using appropriate bulbs/housings for their intended use, and there are several things to consider when "upgrading" your lights. Fogs are not driving lights, low beams are not high beams, and high beams should be noticed when engaged, and left off in the presence of others

KC wouldn't be my first choice for learning about beam patterns or what they're called.
And sure enough, there were some that were new to me, despite being somewhat of an auxiliary light junkie.
And it partially explains why I've never bought a KC light.
You can use any site to show beam patterns a correctly designed driving light will shine forward which is probably why theirs is DOT approved. KC's been around longer than almost any I can remember. They must be doing something right.

If you stick a stupid bright light or aim it incorrectly then its the same as any other light. To each their own I suppose. When I drive in my truck even I am annoyed at trucks running around with there fogs lights on. You folks should try what I suggested park your truck on the side of the road turn you low beams and your fogs on slowly pass your vehicle in the opposite direction the fogs are what will hit your eye. Leaves nice little white dots in them too. I dont see any reason to drive around with fog lights on unless its foggy or I'm out in the middle of nowhere where there are no other cars.

Maybe the morimotos did an exceptional job? entirely possible just usually isn't the case. My fogs sit 33 inches off the ground. You don’t need much more than that to hit a Honda driver straight in they eye.

As discussed earlier, yes, the OE fog lights have a dismal light pattern for what they are supposed to be.
Real fog lights have a good cut-off and can be used at any time without blinding anyone, if they're aimed correctly.

Hi,

as we all love pics - here some references :D

1 Yellow OEM Fogs only ( Alla Lighting H10 LED Fog Lighghts 3000K Amber Yellow)
2 HID Morimoto 55W OEM Projector Low Beam only
3 Fogs and Low Beam
4 High Beam
5 High Beam and LED Bar

Still on the fence on that yellow.
Think now more of getting new Morimoto LED Fogs and try that yellow tint on it.

Mike

Mike, looking at those photos it's painfully obvious that your fog lights don't work as fog lights.
They put light higher than the low beams do, despite being mounted much lower.

It's not just an adjustment issue, unfortunately, as the OE fog lights have such a bad beam pattern that they really can't be adjusted correctly. They're best used as DRL, I think.

Just to make sure, you are referring to these?

Dodge Ram: XB LED - Fog Lights from Morimoto HID

The LED Projector fog lights? Or are you referring to an LED Bulb inside of a fog light housing?

I ran the X8 Projector fog lights on my 12 for several years, no resistors, no issues.

When i upgraded to my 18, i continued the plug and play approach, Just plugged them in. No issues, no resistors, no canbus cancelers, nothing. When i adjust settings for HID headlights the only fog light setting i changed was to disable the fog light drop out. I have had zero issues with the X8 Projector LED fogs

My Suggestion, with them haven worked for several years, is to check your grounds and your connectors. Sometimes the connectors might get loose, which can cause intermittent issues. Make sure your pins are fully seated and making proper contact. Especially since when you bench test the lights they work

The way the canbus system works, is at startup it will check the lights for any lights out. If it detects any issues, it will turn off power to that light, so the reason your factory light might not have worked at first is because it detected an issue, turned off power, then after a power cycle it checked again, and did not find an issue so it kept power on. I would lean towards the issue being more with the Morimoto light, or with the connector. Also, the morimoto staff is very knowledgeable and helpful. giving them a call might throw out an idea on something to check that none of us might think of that could solve the issue. If anyone else has ran into your issue, the manufacturer would be a fantastic place to start for assistance in troubleshooting.
Like you, on my 2015, the finickiest MF’ing truck on the planet when it comes to lighting, I just swapped the OEM fogs with the Morimoto XB LEDs. Didn’t have to OBD nothing in the computer. Plug and play with original harnesses. Couldn’t believe it was that simple. No issues for over a year now.
Here’s a couple of pics of the even low Broadcast pattern, light set up and Fog lights only pattern on the road.
Note, I’ve since changed out my HID bulbs to 5500k so they are whiter than in the photo.

I think I'm going to have to order these morimoto xb fogs as one of my LED bulbs finally went dead. Hopefully they're going to have a sale soon 🤞

I could sell you a very lightly used set. I'm looking for something better.

PM me a price if you dont mind.

What do you not like about them?

I'll have to look up what I ended up paying for them, Opie.
Anyway, they have maybe 5 minutes of usage on them.

What I didn't like was the light output when used in conjunction with good LEDs in the quads.

Oops, and I just realized that I had the ones for the 1500 in mind. They won't fit your 2500.
Once I have the 3500's headlight situation figured out, I can let go of the XBs for that one.

No worries.
I have the HR V4s for my lows in my quad lamps and hoping these XB wont disappoint.

Uh, oh. That's exactly what I'm running, too.

Had I installed the XBs with OE bulbs in the headlights I may have been somewhat impressed, but...
