Do you know what that other hot DRL wire is for?I have a halogen JLUS (in the US) and my DRLs do stay on with my headlights. They actually DIM when I turn the headlights on. I'll also add that when I installed aftermarket LEDs in the DRL fender position, they needed to be low input models. My initial attempts (without the low input bulbs) did in fact turn the DRL off when the headlight was turned on.
I also tried the Oracle HALOs, and tied them into the DRL harness from fenders. They actually DID turn off when I turned the headlights on.
