Mahabharata Drona Parva Chapter 162:2

Mahabharata Drona Parva (Ghatotkacha-badha Parva) Chapter 162:2 And upon each horse was placed a large lamp. Thus was that host lighted up by the Kuru warriors. Set in their places within a short time, those lamps speedily lighted up thy army. Indeed, all the troops, thus made radiant by the foot-soldiers with oil-fed lamps in their hands, looked beautiful like clouds in the nocturnal sky illumined by flashes of lightning. When the Kuru host had thus been illuminated, Drona, endued with the effulgence of fire, scorching everything around, looked radiant, O king, in his golden armour, like the midday sun of blazing ray. The light of those lamps began to be reflected from the golden ornaments, the bright cuirasses and bows, and the well-tempered weapons of the combatants. And maces twined with strings, and bright Parighas, and cars and shafts and darts, as they coursed along, repeatedly created, O Ajamida, by their reflection myriads of lamps. And umbrellas and yak-tails and scimitars and blazing brands, O king, and necklaces of gold, as these were whirled or moved, reflecting that light, looked exceedingly beautiful. Illuminated by the light of those lamps and irradiated by the reflection from weapons and ornaments, that host, O king, blazed up with splendour. Well-tempered and beautiful weapons, red with blood, and whirled by heroes, created a blazing effulgence there, like flashes of lightning in the sky at the end of summer. The faces of warriors, impetuously pursuing foes for striking them down and themselves trembling in the ardour of the rush, looked beautiful like masses of clouds urged on by the wind. As the splendour of the sun becomes fierce on the occasion of the conflagration of a forest full of trees, even so on that terrible night became the splendour of that fierce and illuminated host. Beholding that host of ours illumined, the Parthas also, with great speed, stirring up the foot-soldiers throughout their army, acted like ourselves.
