Hi frnd,
Here's Ur answer:
An electronic device which gives off light by the heating of an element contained with a glass enclosure. The metal base which conducts the electricity may be a barrel with locating pins, or it may have small filament wires protruding from the base. In some cases it is a tube with contacts at either end. When replacing bulbs, especially high intensity bulbs like halogen, be sure to avoid touching the glass. The oil from your fingers will cause the bulb to overheat and burn out quickly. If you do touch the glass, you need to clean it with alcohol and air dry it.
Hope this may be helpful to u.. frndd
