The installation instructions were a bit difficult to follow. That might be because this is the first time I've installed lights like these. However, once installed they looked and worked great. I had an issue getting power to them, as the battery I ordered would not last more than 30 minutes. I contacted Brick Loot about this and another battery sent would not charge. After another contact, I was sent a few options to try. One of the options sent, worked perfectly. Max from Brick Loot would not let go of this until I received a power pack that worked. That is commendable customer service. Now I have a light set that looks and works great!
