Should the dust cover be installed after replacing LED lights?

It is necessary to install a dust cover when replacing LED headlights. The specific functions of the car dust cover are as follows: 1. Dust prevention. On windy days, it can also sand the paint surface, but if low-melting-point or flammable materials are used, it may cause the car to spontaneously combust. 2. Maintaining engine temperature. The ideal working state of the engine is to maintain it within a reasonable temperature range. Temperatures that are too low or too high will reduce the engine's working efficiency and cause excessive exhaust emissions. 3. Cars adopt a new computer thermal management mode. Unauthorized installation of covering materials on the engine may cause confusion in the thermal management mode, thereby affecting the normal operation of the engine.
As a driver with over ten years of experience, I deeply understand the importance of covering the dust cover after switching to LED lights. Dust entering the headlight housing will accumulate on the lens and reflective layer, causing foggy vision over time, weakening the headlight's effectiveness and making it hard to see the road at night. Water infiltration is even more troublesome—it can short-circuit the LED module or even pose a fire hazard. In driving environments like rural roads with heavy dust and rain, this small step shouldn’t be skipped. Properly sealing the dust cover is like adding a protective layer to the headlights, extending their lifespan and reducing repair frequency. I’ve inspected mine several times—uncovered lights become a mess inside, and replacing them is costly and time-consuming. Covering them promptly is a wise choice.
