Car Headlight Maintenance Tips

Headlight maintenance is crucial to creating safe driving conditions. Proper maintenance can significantly lower the risk of road mishaps. When your headlights become cloudy they weaken the car’s light beams. Obviously, this hurts your visibility especially when driving at night. Below you will find common headlight faults that you should look out for.

Car Headlight Maintenance Tips

Yellowing/ fogged lenses – A majority of car lenses are made up of polycarbonate material. Long exposure to the sun’s UV rays and external heat oxidizes this material leading to yellow or cloudy lenses. You will need to have the colored layer polished off of the affected lens parts. Strokes should be firm but gentle. Next you should apply a UV resistant protective coat.

Misaligned headlights – Off-road handling and potholes continually dislodge the position of the car’s headlights. These alterations may not be outwardly visible but they can be detected through specialized checkups. This can require regular headlight maintenance to fix and maintain.

Dimming – It is important to replace headlights as soon as they show the first signs of dimming. Replacing an entire set is recommended even if it’s just one light that has faltered. This ensures that there is even illumination.

Crazing – This is where deep cracking occurs on the lens surface. These cracks don’t affect the overall functioning to an extreme but they are a ghastly sight.

Flaking lens surface – Some types of exteriors are more prone to peel and flake after a few years. When headlight maintenance is neglected, this exposes the bulbs to the elements and also the chance physical damage. It’s better to replace the surface early on to avoid the electrical repairs that are sure to follow.

Surface scratches – These can be removed with the combination of coarse and fine grit sandpaper. The coarse grit is used first to trim off any imperfections. Fine grit comes in to sand off any residue and gives a uniform smooth surface.

Condensation and surface breaches – They take a toll on the electric wiring system of the illuminating structure. They have to be fixed on time to minimize the risk of electric system failure. This kind of repair is quite costly.

Benefits of Headlight Maintenance
