How to Repair Aged Headlights?

Check the degree of aging, cracking, and yellowing of the headlights, and use masking tape to cover the surrounding areas to prevent damage to the paint during sanding. Select sandpaper based on the severity of the headlight condition. For severe cases, start with 180-grit sandpaper for sanding; for milder cases, use 320-grit sandpaper. Use 600-grit sandpaper for sanding, primarily to remove the marks left by the previous sandpaper. Rinse with water and let dry or use a hairdryer to speed up the drying process. Pour the headlight restoration liquid into the atomization cup, heat for about 10 minutes, and then fume the headlight cover until it becomes transparent. Once slightly air-dried, the vehicle is ready for driving.

Last time my car's headlight cover turned yellow and hazy, I tried fixing it myself with good results. I bought a headlight restoration kit that came with sandpaper and polishing compound. First, I gently sanded off the oxidized layer with 2000-grit sandpaper, then polished it to restore clarity—remember to wear gloves to prevent slipping. The whole process took less than an hour and cost only a few dozen yuan, saving me hundreds at a repair shop. Parking in shade daily or using UV protective film can prevent aging, but I needed the car urgently so I DIYed it. Though not professional, it's much clearer now. Long-term headlight cover aging isn't just unsightly; scattered light at night really affects safety, so early treatment is a good habit.

I noticed that after the headlights aged, there were always shadows when driving at night, which obstructed visibility and was quite dangerous, so I need to get them fixed promptly. I often use professional polishing services myself, which are affordable at just two to three hundred yuan, and the technicians will thoroughly clean and restore the brightness. If the lens is cracked, it might need a complete replacement, but trying a repair fluid or kit first can be a convenient option. Don’t forget to check if the bulbs are still working, as sometimes aging also means the bulbs need replacing. Try to park in a garage to avoid accelerating oxidation, and never compromise on safe driving.

Aging headlight covers can be temporarily improved with simple methods. I just apply toothpaste and wipe a few times for a quick brightening effect. For longer-lasting results, buy an online restoration kit – following the instructions for sanding and polishing isn't difficult. In severe cases, replace the entire light assembly or visit a professional shop for refurbishment. Regularly clean surface dirt, like washing after parking under trees to prevent aging, which saves a lot of trouble.
