Installing the HID is as easy as plug and play. The projector requires that you separate the headlight housing to install the projector. But everything else is plug and play.Pretty easy to install? The fiance doesn't think I need a brighter headlight just cause I rarely ride at night. He thinks it's bright enough as is. But when I do ride at night, the HID kit vs the stock one could mean the difference in me seeing the deer a lot sooner vs me racing up to the deer on the side of the road and freaking myself out.
