After the Chanukah lights are kindled, it is customary to recite or sing the Hanerot Halalu hymn.

Hah-nay-roht hah-lah-loo ah-noo mahd-lee-kin
Ahl hah-teh-shoo-oht veh-ahl hah-nee-sim veh-ahl hah-nif-lah-oht
Sheh-ah-see-tah lah-ah-voh-tay-noo bah-ya-meem hah-haym biz-mahn hah-zeh

Eh-lah lir-oh-tahn bil-vahd, keh-day leh-hoh-doht oo-leh-hah-layl leh-shee-meh-khah hah-gah-dohl
Ahl nee-seh-kha veh-ahl nif-lah-oh-teh-khah veh-ahl yeh-shoo-oh-te-khah

Translation:

We kindle these lights [to commemorate] the saving acts, miracles and wonders which You have performed for our forefathers, in those days at this time, through Your holy priests. Throughout the eight days of Chanukah, these lights are sacred, and we are not permitted to make use of them, but only to look at them, in order to offer thanks and praise to Your great Name for Your miracles, for Your wonders and for Your salvations.
