Help with LED lights

[woody258]

I have a led license plate light from my motorcycle that doesn't work. There are two resistors and a third component that I can't identify. Any suggestions to try? I am a novice but have a multimeter and solder gun. Thanks!

3 LED's
2 resistors
1 diode of some sort..

Is your multimeter digital? I found w/ mine I can "tset" LED's by putting it on the lowest ohms setting. W/ the correct polarity an OK LED will light...
Or use a Lithium "button battery" (or any 3 v source..) If all LED's are ok .. then my next guess would be the little diode is fried..
My limited understanding can see why the one resistor is there (3 LED's in series would only need 10.5V -ish not 12v or so. ) to drop the voltage.
not sure of the need for the other or the diode ... Looks easy enough to de-solder every part and test each though..
