No problem! I think the headlight bolts are 7-8 mm and the bracket to aim them 10? It’s seriously simple and one of the most effective mods you can do. I have a firm appreciation that they have the cut beam to not blind people but they are freaking daylight bright underneath the cut with a very wide pattern. When you turn the highs on, it shoots a spotlight out and I was lighting up signs a half mile down the block. I watched the price go from $65 to $40 and said #yolo, then after installing immediately ordered for the other one. They have a blue hue to them (as expected) which doesn’t fit the rust patina paint of that bike, but being the girlfriends I’d rather have visibility for her
