Sounds like you shorted the antennea. Try leaving the lights out and make sure the antennea wire is soldered onto the little clip at the base of the antennea well and then make sure that the antenna, the wire and the clip at the bottom of the antennea is not touching anything metal. If all of the above looks okay, box it back up and head back to radioshack. They're pretty understanding of things and when you tell them that the lights shorted something out, they'll probably exchange it for you as long as you haven't hacked up the inners like me
