I live in the rainy Northwest, and got stopped for a dead brak light. Water was standing in the lens of the left rear light cluster. It had corroded and popped the side maker light and brake light. I soaked the water out and replaced the bulbs, but imagine it will refill with water. Has anyone tried putting a sealant under the lens gasket, replacing the lens gasket, or just tightening the nuts? Ideas? Thanks.
