I recently installed a set of Spyder LED tail lights purchased from Amazon. The first set had one light (left) that had a manufacturing flaws that looked like rough edges along the top. It almost looks like cracked edges. I ordered a replacement set and the left had the same defects so I assumed it is standard for their manufacturing. After searching for posts on the defects I noticed a few people have sealed there Spyders with silicone caulk. How common is it for these to have leaks?
