How can I do it with elisp code.  Highlighting lines starting with
";; [".

Thus in elisp-mode, how to achieve the following

;; [Highlighted line]
;; Some comment 
;; Other comment

Have started with the following, whilst you suggest 
"highlight-lines-matching-regexp".

(defun hl-regexp ()
  (interactive)
  (highlight-regexp ";; [.*" some-face))

(defun hl-elisp ()
  (add-to-list 'auto-mode-alist '("\\.el\\'" . hi-lock-mode))
  (add-hook 'hi-lock-mode-hook 'hlregexp))
