Mbh 7.162.3a

“Sanjaya continued, ‘Then the remnant of the army (of the Kaurava), under the orders of their leaders, were once more disposed in (compact) array. Drona placed himself at the van, and Salya at the rear. And Drona’s son and Sakuni, the son of Suvala, placed themselves on the right and the left flanks. And king Duryodhana himself, O monarch, on that night, busied himself in protecting all the troops. Cheering all the foot-soldiers, O king, Duryodhana said unto them, “Laying aside your great weapons, take ye all blazing lamps in your hands.” Thus commanded by that best of kings, the foot-soldiers joyfully took up burning lamps. The gods and Rishis, Gandharvas and celestial Rishis, and the diverse tribes of Vidyadharas and Apsaras, and Nagas and Yakshas and Uragas and Kinnaras, stationed on the welkin also joyfully took up blazing lamps. Many lamps, filled with sweet-scented oil, were seen to fall from the Regents of the cardinal and the subsidiary points of the compass. For Duryodhana’s sake, many such were seen to come from Narada and Parvata in especial, lighting up that darkness. The (Kaurava) army then, disposed in compact array, looked resplendent on that night with the light of those lamps, the costly ornaments (on the persons of combatants), and the blazing celestial weapons as those were shot or hurled by it. On each car were placed five lamps, and on each infuriated elephant three.[214] And upon each horse was placed a large lamp. Thus was that host lighted up by the Kuru warriors.[215] 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.
