I would try either using original AHL module off you old headlight or buying this eBay one I bought last month. Worked flawlessly and only cost $70 plus shipping. I don't know how to paste the eBay link but this is the title of it. You will need to have it coded after for the adaptive lights to work properly but your turn signal and halo lights should work
