Gauge sized stereo tip

[mpilot]

So the new boat came with a gauge sized stereo. We have a 6 month old so haven't been out at night much this year like we have been in the past. This past Friday we were coming back from dinner around sundown and when it got dark the light on the stereo was so bright it was unbearable. They don't make a dust cap for my stereo, or any other I could find, so I wanted something to dim or cover up the radio. I made a template of it and went to the hardware store on a whim at lunch today. What I found was a rubber sewer cap that's for 3" pipe and is only about an inch tall. I bought it for less than 5 bucks and when I went to cover the boat tonight I tried it and it fits like a glove and blocks the light perfectly. We play music off of my phone so I can still control volume, tracks, etc. I wanted to share in case anyone else was looking for a way to block the light from their gauge sized radio.

mpilot, thanks for the tip.

If you want to cover/dim a screen on a laptop or phone or stereo but still be able to see it, do a search for Rubylith. That is what us amateur astronomers use out in the field or in the observatory to help maintain our dark adaptation.

Where can you buy it from and how easy is it to remove? I don't really want to dim it too much during the day as it is hard to see in the right lights, so I need something I can remove during the day and apply at ight. I don't know why they don't make all boat radios and gauges available in red. Red light (which is the concept that Rubylith operates on) doesn't affect your night vision which is why, for example, divers use red flashlights for night diving.

For anyone out there that uses android phones or tablets on the boat you can also use the Night Mode which allows you to dim the phone to virtually no back-lighting. The only tip I have is just don't forget to turn the app off when your done or you will think your device is dead the next day until you take it into a pitch black room.
