Here is a picture of the instructions that came with the attachment. You can see a flasher was specified.
Note that the attachment is on the Super Fuel globe and not the Over 100 as shown (incorrectly) in the Sinclair book.
Ron,
Peter added that attachment to your decaled globe. I have not found any evidence that the attachments were used on the decaled globes. Its more likely that either the attachments or the decals were used but not both.
