All the flashers in my DM where out when I got it. I played it probably 50 times before I even noticed (how did that happen?). I then rewatched the for sale/trade video and they were out in that too. What was wrong? A fuse was simply too old. It didn't look blown. Actually, it looked fine! I tested it and it was dead. New one = Working flashers.
Great game! I really, really like it.
