i'm having the same issue and it makes the fm/am radio static when in reverse... but on sirius XM it's fine and no static, but I have bulb out errors..
Do you have the 7440 model? Try flipping them 180 degrees - please also leave them outside of your housing so you can see the bulb, if not ALL LEDs are lighting up you need to flip it 180, that will remove the errors.
Keep us updated.
Thank you
