I recently took a power inverter that I've had a couple years and hard-wired it into my truck. I extended the plugs, switch, and LED indicator from the inverter box to particular locations within the truck. In the process of wiring the LED, I accidentally broke one of the leads and need a replacement.

The LED is a bi-color, three lead, 5mm, red/green light. I don't have a whole lot of experience with LEDs, so I need someone's help in finding what I need.

Here's some specifics:
1) Right now I've got the old LED with only the green side working (since the red side anode is broke off). So I know the wiring is done right and there is a complete circuit there.
2) I bought a replacement bulb from RadioShack, which didn't work. So I tested to see what the supplied voltage and current was on the green side and my multi-meter showed 7.9 volts and either 5.04 mA or 50.4 mA (I can't remember where I had the ampmeter set to). The RadioShack bulb required 2.2 Volts and 30mA for the green side.
3) I used the ohm-meter to test the LED lights and the old LED lit up on both the green and red sides (I had to push the test needle into the led plastic to get to the red anode), but it didn't light up for the RadioShack bulb. I assume this means my ohmmeter doesn't supply power low enough for the RadioShack bulb?

Pretty much everywhere I've searched, 2.2 Volts and 30mA is the standard for green diodes. Obviously the old one I have doesn't follow that convention, so if anyone can shed some light on what I'm dealing with, it would be much appreciated. Thanks!
