What can be used to polish yellowed car lights?

[StJulian]

When car lights become yellowed, you can use sandpaper to polish the lights and then apply specialized wax for further polishing. Below is relevant information about car lights: 1. Headlights: The primary purpose of headlights is to illuminate the road and objects ahead, ensuring driving safety. They can also be used to signal overtaking at night by alternating between high and low beams. Headlights are installed on both sides of the front of the car, with 2 or 4 per vehicle. The bulb power ranges from 45~60W for high beams to 25~55W for low beams. 2. Fog lights: Fog lights are installed near or slightly lower than the headlights. They are used in low-visibility conditions such as fog, snow, heavy rain, or dust to illuminate the road and signal to oncoming traffic. The lights are mostly yellow because yellow light has longer wavelengths and better fog-penetrating properties. The bulb power is generally 35W. 3. Reverse lights: Reverse lights are installed at the rear of the car to illuminate the road behind and inform other vehicles and pedestrians that the car is reversing or preparing to reverse. They also function as light signal devices. The lights are white with a power of 28W.
