A light saber model with constraints for a:m 9.5.

The model itself is nothing to get excited about, but the automatic fanning it provides could prove useful.

The Bone Hierarchy looks like this:
main
   shaft
shaft follow [the second half of the light]
light [the first half of the light]


All constraint setup is done in the pose "Constraints".
shaft follow: Translate To shaft.
shaft follow: Orient Like shaft.
shaft follow: Aim Roll At shaft.
This rotates the bone to look in the motion direction.

light: Translate To shaft with Lag=00:00:02.
light: Orient Like shaft with Lag=00:00:02.
light: Roll Like shaft follow.
