Candy cane path lights are perfect for sidewalks, fences, hedges and yards. However, you could use them as Grinch outdoor decoration ideas ... decorations like wreaths or ornaments.
In the same spirit as a festive candy cane ... Grinch motif is more your style, simply swap out the burlap for Grinch-green ribbon. Add a little Santa hat on one side, and you've got a Grinch wreath.
