This fall I stopped in to their shop in the Sacramento area. I had issues that the lights were interfering with my sound systems. They found the tech that installed the lights routed the wires from the lights with the wires of the sound system. It works better now. I Glendas on and one of them had a problem. They took the Glendas off and gave me Darlas for the Glendas. at no cost. I also have Krista's mounted. while there I had them put an erica on the right side. I really like them. They make night time to almost daylight.
