I bought new headlights from eBay. After a couple of months I found condensation inside the housing. Upon removal, I found the glue had melted behind the light sockets. It's creating airflow into the housing.

It's only on the side light, the mini bulb. The directional bulb socket is still good.

What kind of glue is it that I can reapply? And maybe handle the high heat that the engine and/or bulbs are producing,.

That is probably standard hot glue. OE stuff is usually sealed from moisture intrusion by rubber in and around the connectors.

Your best bet is probably to use silicone to plug up the back where the wires go into the connectors (make sure the connectors are together when you do it) but it won't keep moisture from going in around the edges of the plastic where the male and female ends of the connectors meet. Don't force a bunch in otherwise you may not be able to unseal the connectors.

After it dries for a few days, pull the connectors back apart and put dielectric grease on the contacts. It's not foolproof, but that should pretty much solve any moisture intrusion issues. If you live in an area with road salt and any salt spray gets in there it will corrode everything pretty quick if it is left unprotected.

If it doesn't feel flexible at all, I'm definitely going with hot glue. I don't think you would have an issue with standard silicone, but you can find different temp ratings (black, copper, etc.) at the parts store.
