Anybody know whether the Blinky 7 and the Superflash use a 5 mm diameter screw? If so, I am considering using a 5 mm rod to mount some. Thanks.

As a followup to what I found out, the Planet Bike Blinky 7 uses a 4 mm diameter screw. From what I've heard, the superflash uses the same mount. Now I am searching for 4 mm diameter rods.
