I have just fitted mine 23 Mar16 , after they were sitting in the garage for quite a while.
I also had purchased earlier the H4 adaptors. So fitted them both at the same time.
Was fairly straight forward, I am happy with the lights so far but have not actually had a chance to check them out on an open road without interference from other light sources.
I do need to lower them though as the low beam is too high. I also don't think the low beam cut off is as clearly defined as standard H4's. On my ex police bike the headlight adjustment is a bit hard to get to and I have not tried to readjust them as yet.
