What causes car headlights to fill with water? Headlights generate heat when in use. They need proper ventilation to prevent condensation from gathering within the unit, especially when the vehicle isn’t in use. If the outer lens cools down faster than the air inside the headlight unit, condensation can form.

Once the light is inside the box, cut a round hole the same diameter as the end of a heat gun or hair dryer on the other side of the cardboard box.
