I did the Diabolical Inc Slipstream install. I really love the modularity, the fact I have tie-down locations and a built-in shelf to keep things organized, and secure storage.
Pictures don’t do them justice, nor do my photographic skills or equipment (iPhone X). Clean, white light with even spread and more light to the sides. Simply overpowered the headlights.
Aiming them in the rain, probably lower than if used only off-road (want to see if low-beams will work as back-country driving and/or fog lights):
