Yes the green light "RL" comes on when I turn on the lights. The light appears to work normally just not as a stand light. I did find that it appears the LBS had the ground wired to + and the hot wired to - from the hub to the luxos. This did not appear to affect the function of the luxos, I swapped them back and everything is still the same. I wonder if that cooked the taillight. Again, though, the taillight itself works fine when it's getting power, it just stops when it doesn't get power. This is not fun!
