waterproofing headlights

So i searched the site and i found the thread on the taillights where some water leaked in and condenstaion sets in giving the water look and to fix it was to use exterior caulking. I just put on some one pieces up front and the rubber silicone on one of them didnt sit very well and it looks like some water leaked into my headlights. Can I use the caulking to secure the silicone, or is there some other type of adhesvie I should use?

Wow that’s kinda expensive. Any other “caulk” out there that we can use as an alternative?
