2-pin LED?

Hi, guys!

I would like to know whether there are any 2-pin LEDs. I want to change my power and HDD LEDs for some new ones, but I cannot really find ones with 2 pins. Are there any?

Btw, can I actually use a 3-pin LED for my power light? There is one spare pin between PWR ON and PWR OFF pins on the mobo slot, so can I connect a 3-pin LED to it?

Thanks!

95% of LEDs are 2-pin. The only LEDs with 3 or 4 pins are multi-color LEDs.

+1, the majority of LEDs I have seen have been 2 pins.

Ooh. Anatorax is not talking about LED's. He is talking about the motherboard connector for the Power LED. That one spare pin is either connected one of the pins beside it or not corrected at all. And if you look closely at the case connector, I think that you will see that there are only two wires and the center pin is empty.

So, yes. You can change LED's. The simplest way is to use the existing leads and solder a new LED to the end of the wires and then mount it in the case.

Pyroflea, even most multicolored LED's have only two leads. What they do is put two different colored LED's in the same package and connect one backwards across the other. Then the direction of the current flow through the device determines which illuminates.

I was referring to RGB LED's, which have 4 pins. :p
