Light Conditions

In most of the situations we cannot avoid the night time driving. Also we cannot avoid driving in different weather conditions like rainy, cloudy or misty conditions. During these times a car or heavy vehicle can we run without headlamps or light bulbs? Not possible. So headlamps are much needed one for a vehicle movement. Automotive lighting is provided by various sizes and types of light bulbs.Usually bulb has one or two filaments. When electric current flows through a fine wire or filament in the bulb, the filament gets hot and emits visible light. The bulb may fit into a socket which forms part of a lamp.
