Stomp Switch with the red or green led ring

I am wonder how you hook up Stomp Switch with the red or green led ring. Do you do the same as just regular led indicator light (use 4.7K resistor or some other value) or some other circuit?

It's the same, pick a current limiting resistor for the desired brightness, I think the minimum specified is 470 ohms or so.  FYI, I've had a few of these LED rings fail after a few years and have stopped using them.

Hefty

any one else with maybe a little more specific info?

Here's one wired. Blue wire on the LED anode goes to a current limiting resistor, then to +9V.  Resistor value was chosen for the desired brightness of the LED, for this one I used 650 ohms resulting in LED current of just over 11 mA, the red LED had a Vf of 1.78.  The LED cathode on the right is wired directly to the foot switch lug #4, the black wire on lug #5 just below it is ground, which is switched to lug 4 when the circuit is active. 

Notice the empty hole on the left of the LED terminals?  This is a single LED, they also make a common anode 2-color LED, the second cathode would be on the left.  You could wire that to the empty lug #6 and have a different color when the circuit is in standby. 

How you wire the left and right columns is up to you, here lugs 1-2-3 are input and 4-5-6 are output, the shielded leads go to the in/out jacks.  Nothing is grounded when it's bypassed, this was a low-gain circuit with no danger of oscillation.  You can also ground the circuit input, output or both during bypass with slightly different wiring schemes.

I don know what exactly do you mean by this: you need only one two-colored diode to signalize switching on/off for effect? Or one diode circuit made from more led diodes? Or two led diodes, to signalize effect on/off? Can you be more specific?

I was hoping more for specifications for the ring led. I don't have issues with how to wire it up. but thanks

Not sure what you are asking for. It should just be a holder for a regular led that you then provide a regular CLR for.

Can you provide a link to the product page for the one you have. There may be a datasheet with specifications for it.

You prabably think about led-ring as a product, to use it around stompbox switch or anywhere next? Something like this:

There is some specs but I was hoping for a little more specific numbers that some one had used instead of maybe try this or this. It looks like maybe not that many people us them? I would think they would last as long as a regular led if you used the right resistor combinations. Math was never my strong suit in life and I was hoping that someone had done the math already,

Here is a special switch and under article is another item - PCB board for connecting it. With this link we can find something around:

Here is a Q & A from that page at Amplified Parts:
"Current limiting resistors are required. Users have found 1KΩ to work well with the blue and green on 9VDC and 390Ω to work well with the red on 9VDC. P-PC-3PDT-BOARD-X makes for easy wiring the single color versions .For a similar item that doesn't require resistors, see P-LRING-X.
