I just installed some CREE 20W LED bulbs that I purchased from eBay, and got the adaptive headlight error that everyone's talking about. The error would occur a few mins after driving.

I velcro'd the ballast onto the inside of the cover as others suggested. I opened it up again to inspect, and could not figure out what I did wrong.

What is causing the adaptive headlight code to trigger?

I don't remember the ballast being conductive, so even if I velcro'd to the wrong position, hitting the DRL bulb (the middle bulb), it shouldn't short anything out.

Any advice from those who installed successfully with no errors is appreciated. Thanks!
