It seals the hole where the tool is inserted that releases the headlight unit to take it out of the car. Maybe if your car is out in a torrential rainstorm some water could get in the trunk through the front fender wells? When I take my headlights out I can see they have some road dust on the housings and there are some small amounts of road grit inside the headlight cavity. Other than OCD, to which I can certainly relate, are there any specific reasons why you're lightening your car?
