If used for illumination, white or colored lights are suspended from a parachute; and if used for signaling, small briquettes of composition are used which will burn with a brilliant light and produce a meteor effect. By reason of the fact that the rifle light is more scientifically designed and by reason of its size, approximately 6% inches long and 1% inches in diameter, it is capable of quantity pro Fig. 120.--Parachute rifle light. duction, an important feature, which has resulted in the standardizing of the compositions used and the methods of manufacture to such an extent that the rifle light is a rather well-developed pyrotechnic device. When the light is used for signaling purposes it is usually fired to a height of 500 feet. When used for illuminating purposes a lower altitude is attained....
