Has anyone an idea for non working 1/72 nav. lights. I thought I could modify coloured LEDs, cutting off the wires and filing a flat on the top. They would be coloured and glossy if not the correct shape.

Why not make them work? If you’re using LEDs anyway. What size? 3mm

I've checked my LEDs and they're too big. The boat is feeling quite heav at the moment , there's no room in the hull for more batteries and I think running wire from the deck to the superstructure is too fiddly. I'm going to scour Cornwall website for tiny nav. lights.
I need to contact them wrt small ships wheels (steering)

I recently bought some tiny 2mm LED'S from the COMPONENT SHOP on line to use as navigation light and powered them from a CR2032 3v button battery you can buy a battery holder with integral switch for these on ebay for about £2 and the whole lot weighs next to nothing .I stuck the battery holder under the deck and used very thin wires to connect it all up

Looking to finally do the last few bits to finish the boat. Have ordered some 5mm bollards and a small ships wheel from Cornwall Models and will buy some tiny leds from Component Shop. I could well decide to light them up. Did you fit mast head lights as well as on my boat the mast is on the foredeck and will need a separate power supply. Did your battery holder come from Component Shop?

Generally on most of my boats, the LEDs are switched remotely from a 'Turnigy' RC switch, and powered from the main battery using resistors to drop the voltage. If there are multiple LEDs to power, I assemble a resistor board from vero board to have multiple wires coming off it. On the Anchor Handling Supply Vessel, there are 37 LEDs in total.

For the smallest LED's you will need to use SMD (surface mount). The catch being that wire needs to be soldered directly to the body of LEDs which can be tricky on the smaller sizes.
To give some examples:
- 1206 - 3.2mm x 1.6mm
- 0805 - 2mm x 1.25mm
- 0603 - 1.6mm x 0.8mm
- 0402 - 1mm x0.5mm
There are smaller sizes available but soldering wires on something that size is a nightmare! The smallest I have is 0603. Surprisingly these tiny LED's are readily available at very low cost and in a variety of colours. Despite the size they are very bright so keep the current in the 1 to 10mA region.
