I have read the following post on baking a Corvette headlight in the oven to release the glue holding it together:

Wondering if the amount of heat used to release the bond is about the same for all headlights? I am repairing a 2018 Hyundai Elantra sedan headlight that has a loose part on the inside. Thanks in advance.

The heating time and temp will vary based on the adheasive used during the original assembly.
I am sure the Corvette instructions will get you in the ballpark.
Have you searched this on a Hyundai forum or Youtube? I am sure somebody has done this before.

Yes, checking else where. Thanks

Yeah the heat time will vary slightly because again of different type (and amount) of adhesive used but for the most part it's the same. I've done this sort of thing on a few cars through the years and have always followed the "heat to 350F" and -start-tugging-where-you-can thing until I can begin to get the lens and housing to separate. Re: the link you posted I agree with what is posted there. Some people think this just melts or congeals into a mess when baked but it's more like it begins to sweat a little and loosen up. Remember that most non-LED headlights get incredibly hot, so if it were just simply melting at 350F then we'd have cars rolling around everywhere with melted head light assemblies.

The worst thing you may deal with is subsequently actually removing the adhesive to prep it for re-assembly. Ideally you will want to have the adhesive remain on the housing, as it's easier to remove there. If it remains on the light then you'll have to be very careful attempting any sort of clean up or removal as it can crack the lens. I had one head light I was unable to completely remove adhesive from, so I just shaved a fine layer of it off to give room for new adhesive, then applied, and reassembled. A bit janky, but it worked.
