Sometimes just one or two segments of the corner lights can go. This is how you change them. Also note that on the roof of the machine there is a little black controller. You can have the lights 1. Unplugged 2. Flashing 3. Constantly on by changing the configuration of these plugs.

Note that there are 2 types of segments - the top piece has a plug on it - the other pieces slot into each other- ask for a "plug LED strip" or a "connector LED strip"
