I scrapped the red and green light today and made new ones out of a 8mm acryl rod I bought a few weeks ago.
First I made notes about the size ...

Milling down to 6.5mm on my lathe. Anything on a lathe or drill has to be made with a very low RPM or the acrylic rod will melt.....

Marking where the material should stay ...

Milling the contours and drilling a 3.5mm hole for a LED or microbulb.

With a small handsaw I cut away the finished position light.

And here is the finished positon light. A little bit of black color and its ready to be used on the boat.
