I agree with Max.
There's no schematic to the internals of the stock LED headlight controller, and that headlight retails for more than $1000, so use caution. It looks to me like the black/red wire is the high beam power wire, hot all the time, and the circuit is activated by grounding the blue/white through the high/low switch.
If you're unsure of the wiring, another way around it is to use a common automotive relay used for auxiliary horns and lights. It's a good idea anyway since the Darlas draw 4 amps, and it would have it's own fused circuit, and not be taxing the LED circuit. This is the way I'd go, so it would be activated by either high beam or passing button.
