Install was easy, standard positive and ground was not hard to figure out. App downloaded and connected perfectly.. lights go to the music or plenty other options built in. I was truly impressed I have a lot of different light systems on my bike and car so far, these are worth the money spent.
Will update and possibly give 5 stars if they hold the test of time. The sticky stuff they give you is not good enough for these light kits ever.. so I use a combo of super glue And zip ties.. works perfect.
