They sound like they are sealed well...but also silicone is one of the worst things to use to reseal headlights. Outgassing could result in a foggy lens. So word of caution to anyone opening up headlights...do not use silicone...for anything. But if you feel the need to add extra sealant, which I highly recommend, use butyl rubber.
