Automotive halogen headlights are much cheaper to install but suffer from brightness performance and beam shape divergence. By contrast, HID car xenon lights are the brightest, bright enough to blind the driver of an oncoming car. They also have far fewer calories. The latest LED light types are brighter than halogen but lower than HID. However, they make up for this by having a directional mass.

　　Halogen is the older brother, and its technology consists of a tungsten wire heated between arcs. Compacted in a glass bulb. When heated, it glows very brightly. The light also emits a lot of heat as the heating process lags. While the available market light satay is within the 4200k heating limit. But some versions may be borderline. Therefore, energy efficiency remains questionable.

　　The second, brighter, and cooler little brother LED is followed by the automotive lighting family. Based on light-emitting diode technology, its microchip-based claims are 90% more energy efficient. It heats whiter than halogen and is a cleaner and emission-free type.

　　HID is now an improved version of earlier tungsten technology. Actually a new genre of lighting. High-intensity discharge lamps are electric gas discharge lamps. Light is generated by cross-electrode discharge transfer. When they operate in an inert xenon container, it becomes an HID xenon lamp. Housed in translucent or transparent tubes, they are noticeably brighter, and their lighting performance is even better than LED lights. While they may not last as long as LED lights, they last 5 times longer than halogen lamps at about 10,000 hours.
