It does have several colors, it also has 2 or 3 rates of flash timing too. On the mount, I haven't tried to see if my PBSF would fit in the mount that came with this light. To be honest, I wouldn't want to trust my PBSF in that mount either!!

However, for a extra light in the rear, and going on my helmet, and the high visibility (so says my wife), IMO, well worth the $2.50 each.
Also, I have a habit of putting a flashing light in my sock to, it shows up in the rear. Will put one there too. I just want to be seen..
