solar-powered Windex light

Here's an idea for a Windex light if you don't want to run another set of
wires up your mast and haven't converted the anchor light to LED yet:

Put a rheostat in the circut to the anchor light. When sailing, dim the
light until you can just see the Windex. Turn it full up at anchor.

Interesting idea! Thanks!

I put a pair of white LED strips on the spreaders for night light
spreader lights. $10 as bass pro shops.


If those are bright enough pointing up to illuminate the Windex, I think
they will be bright enough reflecting from the sail to do bad things to
your night vision.

I already have a deck light... but it were a good alternate suggestion.

Can you use a rheostat with LEDs?

OR?

That ought to work pretty well for a Windex light as well.
AND save a bunch of trons.

I don't mean to contradict Roger, but LEDs are current opperated deviced.
So a current liniting resistor in serise will reduce the light output.
But the reostat used for a light bulb won't work.
Resistance would likely be way too low.

Can you point me to an appropriate reostat?

More like a variable resistor.

Reostats are usually wire wound for higher current - like a light bulb.

LEDs, at least the one's I'd use for this kind of thing, barely pull
10mA/diode. A single bright white LED running at 12 volts - golly,
I'd start about 200 ohms fixed resistor and see how bright the light is
at 50 feet.
