I'd appreciate any feedback here and thank you in advance.
Okay, I went out, looked at what I have and took some photos. And now I remember. SO, here's the problem as I figured it out then. Might not be true, but it's what I understood at the time and it works.

If you look at the photo with the wires, you will see that I'm not using the side marker plug (in the circle) and I've wired my lights into the front turn signal/parking lamp. That's a three-wire system. The factory side marker is a two-wire. Using the front allowed me to have a side marker and a turn signal. The front bulb has two filaments in it, one on the parking lamp circuit and one on the turn-signal circuit. I think.


I still don't understand why the LEDs from bushwhacker didn't work, but they didn't. They finally quit working completely (I was in a torrential rain storm and they didn't survive that) so I took them off. That was a trick without taking the fenders off. I then used the new lights (seen in the other photo) and wired one to be a side marker and one to be a turn signal. So having the two LEDs effectively gives me a two filament approach.

I can't claim that anything I've said holds water other than it works.

Well, I think I got this all wrong. The fender lights only come on as a marker light and will blink ONLY when the parking lights are on. If they are NOT on, then it does nothing. For some reason, I though I had this figured out. It's been such a long time since I looked at this.

I'm going to have to look at this again and figure out a simple circuit to make this work. Can't be that hard.

Sorry for the confusion.

Thanks jedg. I'm hoping to sort this out some how. I don't mind the lights per say that came with the flares. I just hate they don't work when the lights are on. 😡
Crossing my fingers for a solution and again. Ballsy move to switch those out the way you did.

Shutterbug. Ain't that something. That's exactly what I want it to do and mine do the complete opposite - they only work when the parking and or headlights are off.
I just wish I would have checked them with the lights on. I would have never thought I'd be in this pickle. 🙄

I'm not familiar with the blinker mod but I ASSUME (lol) that you are tapping the blinker positive and running it to the LED feed on the flares? If so, then the problem is probably that the flares get power when the control stalk is moved to the first position or beyond as part of OEM. When the stalk is in the off position there is no power to the flares so the feed from the blinkers is effective. But when the parking lamps (or beyond) are on, hitting the blinker simply adds another power feed to the flares which will do nothing but change the load on each wire. I don't know how that would cause the flares to blink without having two lights on the flares.

You should be able to throw a relay and resistor on each side to get it to work for the most part though...or add a second light or dual filament light.

Thanks 14sport. Do you think a relay would resolve this issue? If so can you elaborate on how to make that work. I imagine it would be placed by the blinker on the front grille since I can't access the flare light directly now that the flare is installed.
I appreciate the help.

Sorry the design will not work because a flasher is not capable of driving the control circuit of a relay. I tested it with both a thermal and electronic (EL-12) relay.

You can put the resistor on whichever circuit you prefer to be dimmer, the directional or marker. I put it on the marker figuring you have them on usually in low light conditions so it will appear brighter anyway. The blinker then has full illumination even during the day.
Two comments:

First, I'm glad to see someone else that has a bench test area. I do this with all wiring before I install.

Second, it's clear that you have a deep understanding of this stuff. I'll be keeping you on my short list of folks to get advice from when I'm confused!
