The Cummins 3918205 Light Bulb is a specialized component designed for use in commercial trucks. Its purpose is to provide reliable and efficient lighting for both interior and exterior applications. This Cummins part is engineered to meet the demanding requirements of commercial vehicle operations, ensuring optimal visibility and performance under various conditions.

Basic Concepts of Light Bulbs

Light bulbs operate on the principle of converting electrical energy into light. There are several types of light bulbs, including incandescent, halogen, and LED. Incandescent bulbs produce light by heating a filament until it glows, while halogen bulbs use a halogen gas to increase the filament’s lifespan and brightness. LED bulbs, on the other hand, use semiconductors to convert electrical energy directly into light, offering greater energy efficiency and longevity ¹. In automotive applications, these bulbs are used for headlights, taillights, interior lighting, and various signaling purposes.
