How to restore dim car headlights
When driving at night or in conditions of limited visibility, one of the most important safety precautions a driver can take is to ensure that their headlights are functioning optimally.
Car headlights don't just experience problems like burnt-out bulbs or weak power. Experience from automotive maintenance experts shows that headlight efficiency can be reduced by scratches on the headlight lens. Let's take a closer look at the causes of dim headlights and how to restore the headlight lens if necessary.
What is the phenomenon of dim headlights?

If you notice that the light from your headlights is no longer as bright as before, it's very likely that your headlights are dimming. Sometimes drivers also notice that their headlights are not only less bright, but the light emitted also has a yellowish, cloudy tint. This could indicate that the headlights are dimming.
Most headlight lenses today are made from thick polycarbonate plastic. Unlike the glass used in older cars, these plastic lenses are scratch-resistant and more durable. However, over time, polycarbonate plastic is affected by UV rays from the sun, and the outer layers begin to break down and degrade. These changes cause the lens to absorb blue light from the bulb, producing a pale yellow light. Cleaning foggy headlights is relatively easy.

Products needed
There are many specialized products on the market today for cleaning car headlights that have become foggy due to UV exposure. Look for products labeled "headlight restoration tool" or "headlight glass restorer".
Additionally, there are several ways to clean cloudy headlights. Toothpaste and baking soda are effective cleaning agents for headlights. Both products have cleaning properties that help remove cloudiness without scratching or damaging the headlights. Polishing compounds like Rain-X can also effectively repair damage caused by UV rays. Overall, you'll need a cleaning kit in your garage or home!

After washing away the dirt, use a cloth to dry the surface of the headlights until there is no water left.
Next, use a specialized headlight restorer. Apply toothpaste or baking soda evenly to the headlight glass. Mix with a little water to create a thick paste. After applying the paste, wait a few minutes for it to dry.
Gently scrub the lamp glass surface in a circular motion with a brush to clean it. You will see the yellowish tint on the glass gradually disappear. Continue scrubbing gently until the glass surface becomes clear.
The final step is to use a clean cloth to wipe away any excess cleaning solution from the lamp glass. You can rinse off any remaining residue with clean water, then dry with a clean cloth.
