Some imagination please.

(defun flash-region (start end &optional window timeout face)
  (with-selected-window (or window (selected-window))
    (let ((ov (make-overlay start end)))
      (overlay-put ov 'window (selected-window))
      (overlay-put ov 'face (or face 'next-error))
      (run-with-timer (or timeout 0.35) nil #'delete-overlay ov)
      nil)))
