With a standard bulb it matters not which way the current flows, it will shine. LEDs are different, they have a required flow direction (I use the word flow because it is easily understood, water and electricity flow) I found this when I bought an LED down light to replace the mizzen mast down light. I tested the unit before installation, all good. Installed it and it didn't go. I had cut off part of the frame of the light with a hacksaw so it would fit and thought I must have damaged it. Happily not so. reversed the wires and all good. By chance when I did the initial test I got them the right way round. Whether this remains so I don't know but all the LEDs I have installed are so.

In about 2006 I decided to change the anchor light to LED. About the only place I could get a bulb was from a company in New Zealand. When i first installed the LED, it did not work. I contacted the company who told me that LED's required reverse polarity. The early LED bulbs did not have integrated circuitry which solved this issue and/or regulated voltage.
To answer your questions, when I installed a LED anchor light in the Series 40 AquaSignal fixture I had to swap wires at the bulb socket. I did not originally install a LED tricolor because it was not available. The bayonet was designed with the two bulb pins offset from one another making the socket polarity sensitive. I had to do this at the socket because the two bulbs (anchor and Tricolor) in the fixture shared a negative in the 3 wire cable. BTW, I did not have the voltage regulator that has been discussed here.
The reversing of polarity is something that was an issue in the early years of marine LED bulbs. Considering the age of Alex's Super Maramu and the fact that he did not originally install the LED's, my first suggestion was to check to see if the polarity was reversed.
