AAG FL 12 flashlight The AAG FL 12 flashlight is designed and marketed by AAG. This flashlight operates at 12 volts. The battery used in the flashlight is a dry cell type. Dry cells only generate electricity for a limited time. Most flashlights use two or three dry cells that fit inside the body. A small lamp is attached to the end of the flashlight body. When the flashlight switch is pressed, the batteries are connected to the lamp and the lamp produces light. When the key is in the on position, the small piece of metal inside the body of the flashlight comes in contact with the positive pole of the battery. As a result, electricity flows to the lamp. In some flashlights, the pressure applied to the battery pushes it forward; As a result, its positive pole collides with the lamp. The flashlights have a glossy surface around the lamp. These surfaces reflect light to distant distances.
