Thanks John for starting this thread.
I'm a big fan of the laser light to normalise my gait and get me going.
For those of you who aren't familiar with it and want to try the light attach it to your waist pointing it down or if you use a frame attaching it to the frame.
It can't be seen in broad daylight but other than that its easily seen indoors or at night etc.
My daughter in law is a physio with a doctorate in falls prevention and she's impressed by its use in PWP who experience FOG in particular.
Worth a try!
