LED Headlight / LED Fog lights
#16
Patman, I'm not sure how using LED lamps in a halogen reflector causes a ton of glare for oncoming drivers. The H11 halogen lamps distribute light out the sides of the bulb and is directed forward by the reflector. LED lamps distribute light out the side of the lamp (one side only) and is also directed forward via the reflector. Same thing, right? The OEM headlight housing has an internal diffuser over the very end of the lamp no matter which type lamp you are using. The LED lights are so much brighter but it is not glare.
Your truck is a 2014 and had no problems using LED lights but I believe the 2015's are different in how the computer processes and controls voltage. In my post I mentioned that I had installed LED headlight lamps in my 2011 and had no problems at all, and resistors were not necessary for them to work. I think the 2009-2014 models were the years where the onboard computers were not as sensitive to the voltage differences and controlled it so closely. I did install PnP load resistor harnesses inline in my 2015, and they did significantly lengthen the time before the right low-beam headlight cuts out. That tells me it's a voltage issue. Turn the light selector switch off and on again, or to the 'always on' headlight position and the right headlight immediately comes back on. Turn the headlights on without the vehicle (and the computer) running and the headlight never goes out. The LED lamp and the driver have both been replaced with new units but the issue still exists so that is pointing to something with the truck's computer.
I think the time is coming where there will not be many electrical alterations permitted by the onboard computers to our trucks...

A led doesn't have the same optics as a halogen filament. There for it hits the reflector in the wrong place and the light gets sent where it shouldn't be. Simple physics halogen filament is different size, length, placement than one COB on a LED board.
Drive up to a flat wall. In low beam you should have a cut off where light stops, with the LEDs up probably have light above that. That's considered glare.

The reflector bowls are different from HID vs LED vs Halogen projectors. All 3 use a lens to focus light, but each one uses a different bowl to optimize performance based on the light output characteristics of the light source.

Very interesting posts explaining light reflections, thanks! When I first installed the LEDs I put one LED lamp in and left the other halogen in for comparison. I went to a warehouse behind my house and shone the low-beams on one of it's walls. I expected to see much of the entire wall lit up on the LED side but to my surprise there was actually a cutoff line just as there was on the halogen light side. After putting in the other LED I went back and the cutoff lines were still there but not as sharply pronounced with the LEDs.
I've taken notice on vehicles that have obviously replaced halogen headlights with LEDs (too old to be factory LEDs), the sight picture coming towards me is just brilliant white light with no haze, just like the newer vehicles with OEM LED headlights. I know that the LED lamps do light up more like a flood light but I actually prefer that to having a pronounced cutoff like with the halogens. This is especially helpful here in PA where I live where there are deer everywhere...

Many thanks for the kind words! It's all a learning experience otherwise I wouldn't have been asking questions, LOL.
A visit to a different, more helpful dealership yesterday revealed that beginning with the 2015's the new Ford trucks are more 'everything computer controlled' than ever before. According to them, even just changing out the OEM halogens for a pair of the optional FORD HID headlights may not work properly because the types of computer modules are custom chosen and installed based on the options selected at the time the vehicle is ordered. Changing one component means changing something else and so on, etc., so there is a good chance that the days of just swapping out one thing for another are largely in the past. Everything is now electronically controlled.
Interestingly enough, the service guy I talked to made pretty much the same comment I had posted previously about no longer being able to add custom electrical equipment to the new trucks and have it work flawlessly anymore...

In my 07, when I first installed LED lights, there were all kinds of gremlins with the signal and brake lamps. No problems at all with the headlight, high beam, or fog.
I changed the flasher relay under the dash, on the driver's side, to an LED relay. That fixed all of my issues. That information may, or may not, help with the headlamp & fog lamp issue. That mod where you ground out the fog lamp pin sounds like it would work for you.
