Some people claim their car tail lights have water ingress. What is the cause? Do they need to be replaced?
Official answer
Many users apply 'paint protection film' (PPF) to their vehicles immediately upon receipt to protect them. However, applying PPF involves using certain cleaning agents. Especially when dealing with external lamps, owners should avoid using cleaning agents containing acidic, alkaline, or surfactant components to prevent corrosion of the lamp surface. Otherwise, it may cause damage to the lamp appearance, such as cracks.
At the same time, please avoid abnormal operations such as high-temperature baking of the lamps to prevent lamp damage. If lamp water ingress occurs, to ensure driving experience, it is recommended to visit a store for inspection and follow the advice of professional maintenance personnel.
