LED Signal Light

I am planning on installing a bulkhead mounted LED light that would alert me when the bilge pump comes on. This should be seen from a 90 degree angle and be red in color and fairly bright. Typically about 5/8" cylindrical, dome light and a nut to tighten it to the back side of the panel.

I am however, having a hard time finding one. Did anyone install a similar one or perhaps know where I could find one as such??

Any info would be appreciated...

Can't help with the light. We use horns. That way you can hear the alarm even when you're not near the panel. Also alerts other people when you aren't on board.

Thanks Gordy that is an awesome diagram set!

I just cannot rotate them. Could you please help with this?

I made a diagram for our bilge pump setup and it looks very similar...

I am installing a high water alarm also, but would like to see the light when steering, especially at night. The alarm definitely wakes up the sleeping crew and they are not happy...

Why use an LED? Red 5/16" incandescent panel lights are easily obtained and cost about $2.00.

Hey Gord,
Thanks for the wiring diagrams. All my four bilge pump switches & fuses are in the same panel. Could I just wire them thru a single buzzer or would I need one for each circuit?
Thanks for tha advice.

An incandescent light can rob amps from the pump... I have one here that I wanted to use but it takes 1.2 amps (Cole Hersee) and it cost $12. I was told an LED is about $15 or so (if I could only find one)...

Don't overthink this. If the conductors are size properly, a small incandescent indicator will not appreciably effect the performance of the pump. The C-H are not very efficient. There are panel lights available that draw << 300 mA. Check Allied Electronics.

Here is a link to the Allied site. Lots of LEDs and incandescents: Search results for "panel indicator lights 12 volt dc" - Allied Electronics

Thanks Charlie, I already installed a small incandescent from an unknown maker. I draws only .7 amps...It is bright and works well!
