What can I do about the MG4 rear taillights fogging up with water droplets?

Tail lights fog up with water droplets, which can be caused by a number of things, including ambient humidity, temperature changes, and sealing issues in the light fixture itself.

The first thing you need to check is the seal and appearance of the lampshade for breakage. Whether it is a headlight or a tail light, the lampshade is waterproof with a seal, but the headlight is also equipped with a breathable design, one is to let the air flow to cool the heat generated by the headlight, and the second is to protect the bulb and regulate the balance of air pressure inside and outside the headlight. After the car rained or washed, the air is humid, the temperature difference between inside and outside, there will be small droplets of fog in the lights, the relatively slight fog in the lights do not have to worry too much, as long as the sunlight or turn on the lights for a period of time, the use of the heat of the lights to disperse the fog and moisture Water vapor and water droplets will be discharged quickly, does not affect the normal use of the lights.

CHECK SEALING: Check the seals of the taillights for breakage or deterioration. If there are gaps in the headlights, especially if the headlights have been modified, the housings may not be sealing properly and need to be inspected at a service facility, which may require new headlights or taking the taillights apart and resealing them.

Use a dehumidifying device: If you're in a high humidity environment, consider using a dehumidifier to reduce the humidity in your vehicle and reduce the likelihood of fogging tail lights.
