Official summary
Servicenews article - The headlights in the Civic Hatchback are semi-sealed and have ventilation holes to help prevent heat deformation. When air flows in and out, however, it also includes any moisture that?s in it. If the air outside of the headlights is cooler than the temperature of the air inside them, the headlights can fog up, just like a windshield on a cold day.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
