💡 "My headlights act up every once in a while..."
It's Pennsylvania. We use salt. This is a common complaint.
This AFS (Adaptive Front Lighting) module looked almost perfect from the outside. The only clue? One tiny green spot of corrosion inside the connector.
Once we opened it up... the damage told a very different story.
❄️ Winter road salt in PA doesn't just rust frames, brake lines and exhausts, it creeps into electrical connectors, modules, sensors, and wiring. By the time your headlights, warning lights, or electronics start acting up, corrosion may already be spreading.
Don't ignore intermittent electrical problems. They rarely fix themselves, and they usually get more expensive.
