That one does require a bit of patience and probably several tries to get. The first thing you need to do, is break the locks on the two centre lights. Keep trying for a horizontal stripe until you get one in the main box. Then carefully clear other colours out of the way until you have a path to the centre that aligns with a lock. Once you clear the locks, try to get a vertical stripe in both outer columns. Then create a horizontal one in the middle box, and align it the same way you did you clear the locks. If you are lucky, that will clear both outer columns at once, but if not just keep trying until you get a vertical stripe in the last column.

It took me ages to learn how to do this effectively but it helped enormously once I was able to TT, so I had unlimited tries.
