Thanks - I need to look into this. Might not work tho - since the halo has two inputs wires, depending on which color you want to activate, rather than just one. I'll review this wiring diagram on the Amazon link you shared.
I gave up on getting the turn signals to blink so that I could get them installed for now and at least aim them and drive the truck while I look for a better solution.

The low beams are bright as hell. A massive improvement. And they were pretty easy to get adjusted with a phillips screwdriver and a wall.

I think my lows are aimed a tad bit too high still, as I am getting people flashing their brights at me. So I will drop them down a bit more.
The high beams are aimed super weird out of the box. They both aim to the exact CENTER of the road about 100 yards in front of the truck, overlapping each other, like a massive spotlight. Very unhelpful and silly. I managed to raise them a bit so they're shining ahead of the vehicle rather down on the road, but they're still overlapping each other. I need some left/right adjustability on the high beams to adjust them away from center and make them useful. I don't see an adjuster screw for left/right on the high beams - so I've contacted TEQ Customs to ask about it.
More on this as I get it sorted.
