On the stern of my yacht, I have a running light on the end of a SS tube.
The glass is gone. On the base for the glass, R and G are embossed, meaning
to me that one should orient the glass in a red/green way. The front
running light is red and green. Is it the same for the stern? I can't find
one of the glasses to save my life, and may just have to replace the whole
damn thing. Or, is the rear light clear?
