The Barracude Dinamik light was pretty easy to install, took a little finesse to get the light mounted flush to the frame of the headlight housing. Electrical was pretty straight forward. Black is ground, Yellow is Highbeam and White is Lowbeam. Just took some splicing and standard electical crimpers and connectors 13-16 gauge. Mounting it on the Bike was cake. 35W bulb for both Low and High, but the reflector seems to spread the light evenly and more intense. Seems to be brighter than stock. Looks great and very happy with the purchase. Thanks Jeff for you assistance on this.
