Hi,
Unfortunately, I’m away from my notes at the moment but I have a strong suspicion that the dimensions or colour are not mentioned. However, there is nothing to say that the flash wasn’t worn in a dissimilar fashion by different divisions.
I’m not sure if this link works, but if it does it should show a picture of the flash and badge being worn:
