Hey guys-
I am wanting to change some green leds to red ones on a hot-swap cage. Turns out to be a pain in the butt. I took apart the unit easy enough, but a little surprised at what I found inside.
There are long button extender poles with leds in the end of them. Easy enough to pull the led out but the leds in the unit have 3 wires (red,white,green) and the red leds I bought only have 2 (positive and negative).

What is the 3rd wire on the led in the unit? maybe a multicolor led?
If anyones knows, to make it work would I hook two wires to the positive?
Did I just get the wrong led? the third lead just confused me...

HELP!

You still hook up a standard led with two legs, just find out witch is neg and pos with a multimeter, you might need a resistor.

personally, i like the contrast that the green provides.
i'm sorry i don't have much more to contribute.

perhaps it would help us more if you could provide a close up of what one of those connections looks like up close on one of the existing green LED's
i don't think it's a multicolor; those typically have four contact points.

Those are dual color LEDs. One wire is a ground and the other two are the positive terminals for the different colors. You chose the color by changing which pin you connect to the positive supply.

so I would hook up both of the positive wires (green, red)to the positive, and the white to the neg?

Not really, I'm assuming that the green wire would be for the green part of the led and the red for the red part of the led. But you want the red led to always to be on, so I would try hooking the up the green and white wire to the red led . Or maybe even just switching the green and red wire sides on the stock led.

Thats exactly what I did. I never saw the lights switch off of green before, so now that I have them switched, I am assuming that they will switch from red to green when a drive fails.
