Inadequate Setup

Moisture penetration can result from improper installation during production or aftermarket changes such changing bulbs or lenses, which might undermine the integrity of the seals.

Applying pressure to wash

If the seals are already compromised or damaged, high-pressure washing the car, especially in the vicinity of the lights, may push water past them.
