We have installed units in the low beam of our F798's from Futurevision HID, he is an inmate and runs a vendor thread.
He supplies a special unit configured for the CANBUS that does not give error messages. No complaints and he has always given great service. We did our Guzzis with his units some years ago and they are still going strong .
I looked into intslalling his Projector Conversion as it would be a far better beam pattern than relying on the OEM reflector, but unfortunately it won't fit. Having said that the beam pattern is quite acceptable with his units.
Don't just look at it - Ride the bloody thing!
