The Light actually learned from Ra's al Guhl that Nightwing was with Brion, Halo and Forager. Though Ra's isn't a member of the Light, it was mentioned in "Home Fires" that the Light was still communicating with them.

Most likely, the Light had Lobo target Forager to throw suspicion as to who really hired Lobo in the first place.
