In 2254, illusory versions of two horses owned by Christopher Pike – Tango and Mary Lou – each wore a bridle. The bridles and everything else in the illusion were telepathically created by the Talosians. (TOS: "The Cage" , "The Menagerie, Part I" , "The Menagerie, Part II" ) Jean-Luc Picard's holographic horse from the Equestrian Adventure holoprogram also wore a bridle. (TNG: "Pen Pals" )
