How can moisture inside the headlights cause bulbs to burn out faster?

Water condensation inside the headlight can lead to short circuits.
Moisture can cause corrosion on the bulb’s contacts, reducing electrical flow and increasing resistance.
In extreme cases, water can cause the bulb to explode due to rapid temperature changes.
Sealing leaks and using silica gel packs can help prevent condensation issues.

Effects of Moisture in the Headlights:

Short Circuits: Moisture inside the housing can cause electrical short circuits, which can quickly burn out bulbs.
Corrosion: Water can cause corrosion on the bulbs contacts o r within the socket, leading to poor electrical connections and overheating.
Thermal Stress: In extreme cases, moisture inside the light housing can cause a rapid temperature change when the light is turned on, potentially leading to bulb explosion o r damage.
Preventative Measures: To avoid moisture buildup, ensure the headlight housing is properly sealed and consider using silica gel packs to absorb moisture.
