I was hoping Paul_in_Maryland would check in on this thread. He is our resident expert on traffic wands. I do not know of a wand that fits the A2.
I do not completely understand the battery use argument against the A2. It would not be different than any other Surefire. Any 2 cell light will use expensive batteries at a quick rate for a traffic wand.
The problem is that the F28 traffic wand is too big for the A2. Too big is a solvable problem.
I scrounged a rubber bushing of the correct size. This one came from a ¾" PVC coupling. It just happens to be about a perfect size.

The fit is tight, but fairly easy to assemble. As a bonus, when using the wand with the LEDs, it makes a super marker light that will run for hours. On incan, it looks like any other 2 cell SF.
