Looking for some 5mm LEDs

I'm looking for some 5mm red/green common cathode LEDs. At least I'm pretty sure it is common cathode. I'm replacing some LEDs in something. I get a positive reading when hooking up the common lead to the middle leg and the other lead to either outer leg. I wanted to verify that - is cathode before ordering. Everything I've found confirms that. Except for the only place I've found what I'm looking for. The link below says cathode is +.

Dual Color Red/Green LEDs - 5MM Products Model: DUAL-LED-5MM-RDGN [DUAL-LED-5MM-RDGN] : Performance-PCs.com, ... sleeve it and they will come

I'm not having a whole lot of luck trying to find what I'm looking for. Does anybody know of another source to find some? I prefer a clear lens. The place above wants over $3 for shipping 4 LEDs... That's even if those are the correct ones I'm looking for.

Yes, you'd need a common cathode dual color LED. Can't help you on where to get them though.
