... 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. -- Roger Long Interesting idea! Thanks! -- "j" ganz @@ www.sailnow.com |

... "cavelamb himself" wrote 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. -- Roger Long I already have a deck light... but it were a good alternate suggestion. Can you use a rheostat with LEDs? -- "j" ganz @@ www.sailnow.com |

I put a pair of white LED strips on the spreaders for night light spreader lights. $10 as bass pro shops. That ought to work pretty well for a Windex light as well. AND save a bunch of trons.

But the reostat used for a light bulb won't work. Resistance would likely be way too low. Richard -- (remove the X to email) Now just why the HELL do I have to press 1 for English?

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. ???
