Replaces the stock headlight rim iot fit an ece certified 7" LED headlight assembly, in this case from MOTEA.com, Part No A031414, “Craftride LED Halo 7” for Harley Davidson ECE". Pretty much plug and play for the H4 part. To use the halo ring on that LED you can use (+) off that little “parking light”. The halo will light up if you power up your bike then. Insert self-securing m5 nuts into the recesses and use the original mounting screws.

Optimized for printing in PA6-CF so the thread is a bit wider to compensate for the higher friction, but will work with ABS/ASA too.
