Genuine Harley New Old Stock OEM Front Bullet Style Turn signal Assembly. Brand New. This has a single filament bulb. It has 2 wires coming from it, one is a ground and the other is the hot wire for the bulb. The socket assembly in it is part number 67800148. I believe this type of signal is used on International Models.
Used on Harley '18-later Softail International Models. Maybe other years and models as well. Check your parts catalog to be sure it fits your bike.
