Ct5 platinum sports high brake lights always have white fog.

when you unscrew the screw, you will see a sealing ring, which is damaged or aged, or the screw is not tightened.

under normal circumstances, if the temperature difference between the inside and outside of the car is large due to the weather, it is normal for the lights to fog. Lights have air holes for heat dissipation. After the lights are turned off, cold air enters the lights with the air holes, and fog appears on the lampshade. As long as it is not leaking, it will be fine.
