You could find some two sided 3m tape or glue and put it back on yourself.
Ask them to send you the lights to do it yourself
Find glue and glue them back on.
I just bought a 30IOK and have read on here before I bought that there may have been a glue issue from the factory during certain manufacturer dates. One of the owners stated that during their PDI the tech noticed it, made the comment that it just be a bad glue batch as it was the 8th he had seen like this. The one I own does not appear to have an issue.
