I can tell you DO NOT USE SILICONE

what should I use to re-apply around outside lights, windows, corners, and anything else outside needing a water tight seal?

Hopefully there is something I could use for everything, thank you

For vertical surfaces I use non sag formula ProFlex, for horizontal caulking I use Dicor self leveling lap sealant. If you're going to search out Dicor make sure you understand which version you're buying, and why, as self leveling isn't suitable at all for use on vertical surfaces.

Dicor. Get the original, not the specialized variations that are for only one specific material. I hadn't purchased any in the last 3 years and when I went to get a couple tubes at the local dealership, I was shocked at all the variations now. I searched out the original. I didn't want to chance the specialized flavors, even with Dicor.
