    And I presume there'll be lit port and starboard navigation lights and a stern light?

    The stern light is already there, just need the yellow tow light above it on the mast.
    The marker lights will be on the wheelhouse roof, some coloured LEDs in coloured housings.
    Trying to decide how to give power to them as Ill either need to modify my battery lead with another JST offshoot or fit a few cells in the wheelhouse. Im not planning to add any detail in there anyway. But thats extra weight forward of CG and the boat may still need a bit more balast aft to keep the stern low in the water as it is.

    A quick stop by the local hobby shop on the way home from work (which lasted far longer than it needed to due to liberal browsing) has provided me with more bulbs.
    So armed with a yellow sharpie marker I added a tow light to the rear of the mast.

    Some more tubes glued to the mast for wire routing, wrapped to disguse it as I am NOT routing any more wires down the mast. Its not pretty but it works.

    Two more switches added inside the wheelhouse, only one so far wired in. Trying to decide how to use the other. Maybe headlamp?

    But here is the thing lit up in the dark.

    Tried it in the dark at about 20', pretty visible, although the yellow isnt very distinct. A bit of thinned yellow paint perhaps.

    Trevor,

    You can buy “stained glass” paints, which work passably well. I’m not sure of the make I bought, but “Pebeo” seems to be the current favourite. You’d probably want the orange rather than a yellow, and do leave them to dry for a long time before turning on, or the paint bubbles when the bulb gets hot. Though whether you’d want to pay £4.75 to colour one lamp is another question! Maybe the marker pens?

    Those paints look interesting but for one bulb, as you say, probably not worth it.

    Ive got the lighting finished.

    Still have to make the lens cover for the headlamp, but its wired up. Im rather pleased in the headlamp mount, which is one of the bolster hoops from Mike Williams LNWR D12 kit.

    2 more switches wired up to a different power supply, a 9V in the wheelhouse mounted in a wooden battery box. Holds it quite firmly actually.

    A few more details on the cabin and the bullwarks and itll be done.
    Then I can get on to painting.

    Trevor,

    Your nav lights are very bright, too much IMO.

    If you have them wired in parallel, try wiring them in series. It’ll dim them nicely, and make the batteries last rather longer.

    I dont think I can actually at this point. Ive already sealed up the roof and the battery also supplies the headlamp which I dont want to dim.
    I could try to modify the LED itself or its housing to diffuse and block some of the light. Also the photo is quite overexposed so it does seem brighter than it actually is. The tops of those covers will be painted a suitable colour so that should block the upwards light. I can also paint the back corner of each so more light is blocked where its unneeded.
