Having good visibility can help decrease the chance of an accident happening. If you notice that the headlights are becoming dimmer, it may be a sign that your headlights are going out. Check the lens, as sometimes that will get foggy with age. It is recommended to get a new lens so that the light can be better from the headlights. Also make sure to inspect the taillights on the vehicle as well. This can help others that might be behind you, notice where the vehicle is if it is dark out. Also check the blinkers on the vehicle. The blinkers alert those around you to what way you will be turning. Without blinkers, an accident can occur.
Headlights rarely indicate that they are about to quit working. This is why it is good to know the estimated life of your headlights. You may not know their exact life span because there are so many factors that affect it. This lifespan estimate is developed using a complex formula involving voltage, watts, lumens, and a few other factors. Each contributing factor, as well as real world testing, is crunched together and an approximate number is determined. If you are getting near the end of this estimated life then it is a good idea to purchase an extra set of bulbs to keep until needed.
Headlight systems require periodic maintenance. Sealed beam headlights are modular so when the filament burns out, the entire unit is replaced. Most vehicles use headlight lens-reflector assemblies that are considered a part of the vehicle. This allows just the bulb to be replaced when it fails. Be sure not to touch the glass bulb with bare hands. The oil or moisture from human skin can cause the bulb to overheat and burn out prematurely. Headlight aim must be properly checked and adjusted frequently. Misaimed lamps can harm other driver’s vision and stop you from seeing effectively at night. Over time the headlight lens can deteriorate. Plastic lenses can often become cloudy or discolored. If you notice anything that causes the headlights to not illuminate efficiently, make sure to bring the vehicle in as soon as possible so we can inspect it for you.
