The light was a metaphor for Asgard culture. Consider that we now call the European Middle Ages the "Dark Ages", a time before the Renaissance and the Age of Discovery. The Asgard consider the authoritarian, ruthless time before they came to power and ultimately dominion to be a dark time. 

"Long before the birth of Light, there was Darkness," means that the Dark Elves were the power before the light of Asgard brought about revolutionary change in the realms.
