Inverness have snapped up former Barnet defender Kenny Gillet following a successful trial.
The 24-year-old Frenchman has spent the last three years with Barnet, making 89 starts.
He left this summer after a contract dispute and turned down an improved offer from the club's new manager Mark Stimson.
Inverness boss Terry Butcher said: "Kenny has impressed us.
"He's still young but has good experience and gives us the left-side balance and competition we've looked for."
Bordeaux-born Gillet, primarily a left-back, played at Caen before heading to the United Kingdom.
