Types of headlights: incandescent, halogen, xenon, and fog lights.

Many of us take our vehicles for granted. We jump into them, start them up and take off. But, do you ever stop to think how hard and how safe it would be to go anywhere at night without headlights? Sure, most streets are lit, but it would definitely be very difficult to drive at night without illumination.

There are many types of headlights available and depending on the your current use and preference, you may want to consider your options.

- The incandescent headlight is the most common used by America car manufacturers. The light comes from the filament. As an electrical current runs through the filament, it glows and gives off light.

- Another popular type of headlight is halogen. Halogen is a newer technology. It shares the use of a filament with the incandescent light, but its differences make it better. First, it uses a thinner filament. This allows the light to produce brighter white light than its incandescent cousin. Second, it is filled with halogen gas. The gas allows the filament to burn longer and thus extends the life of the headlight.

- The next evolution in “gassy” bulbs are xenon headlights. Like halogen, xenon headlights use gas to achieve a whiter light. Unlike halogen, xenon headlights don’t use filament. They use electrodes instead. These electrodes are encased in a bulb filled with xenon gas. This technology also allows the bulb or headlight to burn much longer. As you can imagine, xenon headlights are more expensive.

- Note that standard driving lights provide a visual range of about 1,000 feet. Pencil beam headlights can double that range. The bulbs are usually for off-road use, they are not street legal. They burn so bright that they are considered a danger to other drivers.

- Fog lights are another type of headlight. It’s all about the angle for fog lights. They are designed to be pointed downward to increase visibility during rain, snow or fog. Light is not reflected off the elements and back into the driver’s eyes. As you get into your vehicle next, think about your headlights. You have many different options. Make sure the light that lights your way is right for you.
