Omnidirectional floodlights on exited submersibles

When you get out, the sub should light up. That's about it. It would be fine, if it was just one sub at a time.

So when you go park your Prawn/Seamoth, it illuminates the area around it, making it easy to find and get back in if you get turned around.

If you get teleported out- the same. Heck, your PDA should go "uhh, why are you out of your sub all of a sudden? It's over here BTW, since there are large predators around." And pop an arrow to the sub that's now brightly lit up.
