Thank you, the buoys are modeled after the Dutch (Netherlands, Europe) large water versions. Its a good idea to make them more visible at night, only rotating parts use alot off electricity what means it will eventually stop giving light in the night. Also the real life versions have a blinking light, I wanted to recreate that.
The buoys are being picked up by the radar so you can always use that to "see" the buoys

Nice job man! Quick question and suggestion. First off, maybe put a rotating spotlight on this bouy instead of a single light? This would help it be a bit more noticeable for bigger ships so they don't get confused. Also, what style bouy is this supposed to be modeled after? Like European? American? Asian? Idk. Thats all, really love it and i hope you can let me make a few adjustments to a few bouys for the sake of realism. Take care!
