Hello Mustang Community!
I have a set of S650 style headlights and Opt7 sequential switchback led turn signals for my bumper.
The setup of the lights look amazing but the issue that I'm having is the flash pattern is off and not in sync at all. This is not a hyper flash issue or an issue with my Opt7 lights at all. It all works but the flash pattern is just not the same and I've tried everything that I can think of to get the pattern to match.
My headlight has a longer stroll versus the opt 7 lights have a shorter stroll and the flash is almost double the speed of my headlights. The S650 style headlight flasher wire is tapped right into the bumper blinker to receive power for the blinker.
I've tried resistors on the S650 style headlight blinker wire to try to speed it up and I've tried resistors on the opt7 lights trying to slow it down with no luck on getting the pattern to match.
The last thing I tried that actually had me excited with 50% success was adding an adjustable flash relay in line with the load wire. It was a 3 prong relay with a ground, line in from the positive blinker wire and load out to the blinker wire of the headlight. I was able to adjust the speed to get it to match exactly and it seemed to work perfect until I actually cranked the car up. This seems to bypass the relay altogether and the relay that I setup for each headlight starts buzzing when the flash is engaged. This made me immediately disconnect it in fear of messing something up.
I've attached a relay of the pictures that I've tried which gives me some hope.
I've looked on the forums and searched all over with no actual resolution. I've also reached out to the company for the headlights with no resolution and still waiting to hear back from Opt 7.
I've tried attaching a video recording to show the issue but unfortunately the file size is too large.
Hopefully I'm not breaking the rules with adding the link to the video on my shared drive but this is the only thing I can think of to make it visible.

In the video, you'll see the pattern is off an this was the results of it overriding the adjustable relay when I had the pattern exactly the same

Does anyone have any idea on what I can do to get these lights in sync?
