Mind if I ask where you got them and how much you paid?Looks good so far. Your testing has convinced me 100%. To the point I just bought a pair of clean SX Led assemblies online. The wiring, wrap, and length is so professionally done. Plus you drafted out schematics. Are you an engineer by any chance?
resistors should correct the flicker.I’m still testing. Everything but low beams works flawlessly; I’m having an issue with the low beams flickering when the car is running. They don’t flicker when off. It’s likely going to require a load resistor and maybe a relay. I have some resistors coming today. More to follow.
