Daining pop-ups?

[ElBichoMalo]

Seems common to install a pop-cleat or cleats and pop-up bow light. I have searched, read plenty, think I know which bits I want and which you all have used. What I haven't found is anything about draining these. Seems Accon has provisions for a cup and drain tube type configuration. What are you all doing for this? Is it okay to just let them drain (I assume it would be minimal amount of water) into the anchor locker? Again, what are all of you who are running these doing?

Thanks,
Evan.
