Hi.
You're right, new HIM vinyls aren't being printed anymore. The last HIM releases before their farewell were the remastered CD's and vinyls of the first four albums (2014). There were 2 vinyl versions of each album, normal black LP and a colored double LP w/ bonus tracks. The normal ones were released together in a box set, but also sold seperately:

Dark Light is kinda hard to find on vinyl. I think there were two prints, the other for USA and the other for EU. People are selling those for like 200 dollars nowadays. I don't have a copy either.
Check out Ebay and Discogs, I am sure you will find something. Good luck
