Headlights' main purpose is to give you a clear vision of the road ahead. Located at the front end of the vehicle, the headlight serves as the eye of the vehicle and the sun of the driver to see the road during poor visibility conditions not just during the night but also during rain and fog. Didn't we mention "fog"? You might ask why you should use the headlights instead of fog lights during foggy condition. The reason is simple, if you don't have any fog lights, you should consider turning your headlights on for other drivers to see your vehicle at the same time to see the road clearly. Some studies might suggest that fog lights do not actually make any difference when use during foggy conditions as compared to the headlights. The yellow beam does not give the assurance of clearer road. And although fog lights are part of the standard features of some vehicles, headlight should also be used during foggy condition for it is located where other drivers can see it better.
Jetta headlights are attached on the header panel which also houses the radiator and grille. The headlights are made from sealed-beam construction that keeps moist, dust, and water vapor from entering the headlight that could quickly deteriorate and decrease the quality of the headlights. And because Jetta headlights are guaranteed to have great quality, it is certain that the headlights will last for long.
