The DRL function simply connects the high beam bulbs in series giving about 7 volts to each. I don't know of an LED high beam that will light below around 8.5 volts so the DRLs automatically get defeated.
On our '06 that's exactly what I wanted when I switched to LED high beam bulbs because I'd installed halo fixtures and made them the DRLs. Really looks sharp!
