Driving lights are specially designed auxiliary lights that are utilized for driving in areas where there is no other light source. They are normally found on 4×4 vehicles that will be driving in areas of complete darkness. These kinds of lights are extremely important when one is driving long distances in the dark. They provide a driver with good night vision, allowing alertness and concentration to be maintained. There are many brands that design and manufacture driving lights, with some being more costly than others. Some examples of brands are IPF, Hella, Cibie, Light force, and others.
The two most common types of driving lights used are halogen or high-intensity discharge (HID). Halogen lamps are designed with filaments made of tungsten, which are contained within an inert gas. There is also halogen in small amounts, which when combined with the tungsten filament, produces a chemical reaction that gives off a bright light. The temperature at which a halogen lamp operates is much higher than that of a normal gas lamp. The light that it produces is of a higher color temperature than that of regular lamps. This makes it ideal for lighting up the areas in front of the vehicle.

High-intensity discharge driving lights are able to produce near daylight quality light and brightness. The light produced by HID lamps is much more powerful than that of the halogen lamps. This is because it does not use filaments like ordinary or halogen lights. Instead, it utilizes xenon gas, which is ignited through an intense electrical current. The gas does not take time to heat up, and within a second, it will have reached its operating temperature. The light that is produced is much whiter than that of normal lamps. This is because the light will change its color as the temperature increases, going from yellow to white and then to a blue white color. The color temperature of HID lights is in the region of 4100 to 4300° Kelvin, while a halogen lamp will normally have a color temperature of 2200° Kelvin. These lights are also very economic in the energy that they use, because once the gas is ignited, they only require a small amount of current to maintain this light, which is usually around three amps.
Both types of lamps will provide excellent lighting, giving you excellent visibility while you are driving in areas of complete darkness. They are more costly than regular lamps, with the HID lamps being the most expensive. However, if you can afford it, they are well worth the investment, and they will last much longer than conventional driving lights.
