Sometimes it happens that the glass has a crack in it. Moisture enters the light and condenses on the electronics PCBs over time.
Usually the result is noticeable when the light is no longer working.
The first to fail are the hazard tail light and the brake light.
In this case, it is necessary to restore the electronics on the light.
In addition, we also varnished PCB to allow more time to react in the future.
The varnish does not protect against long-term exposure to moisture or water, but it does contribute to a longer lifespan in humid environments.
