I was pretty curious about these as well. I love my XD HIDs for the low beams, so I was kinda hoping these would work in the dimming/flicker free combo. Seems they're about the same as the morimotos with flicker links though; full brightness all the time, or low brightness drl with flicker.

Looks like if you want dim DRLs and no flicker, you're going to need to get a pretty involved setup with actual logic to receive the signal from the car and then apply an appropriate voltage to the LEDs. Seems possible, but it's gonna take some tinkering. I'm not sure it's worth rigging up an Arduino to control my high beam intensity haha...
