Almost forgot to answer - You were right on the money. The two LED's I ordered fail to work in other lighting spots. Odd chance of ordering two bad LED's.Haven't actually swapped mine yet.. have the LED's.. just need to find time to do it.
Have you got any others that you can test with to see if they work? Or maybe plug the ones you got in the door lights, since they are readily accessible... just to test them? You might of got some bad ones...
