About ten years ago, I found a string of Christmas lights that perfectly matched the chase lights seen on so many game shows -- all white bulbs, a two-on two-off pattern, they consistently chased in only one direction... plus they even had a dial for variable speed.
Well, time has passed, and they don't work so well anymore. For the past couple of years, I've tried to find an identical set, but all I can find are the newer types that display various patterns that chase at inconsistent speeds and directions. Has anybody recently encountered any commercial Christmas lights that mimic the chase pattern traditionally found on game shows?
