Good news, and bad news. The good news is the cord works and the lights on top work. The bad news is the lights on the bottom don't work. I think it might be blown out bulbs.
Can these type of bulbs be purchased at home depot?
Dunno - why don't you take the blown out ones to HD and ask?
If they're blackened near the ends they're more likely blown out, but after being shipped there's no telling...
Along those lines, they might still be good but just got jostled out of position during shipping - did you try to reseat them first?
You can also try swapping bulbs top-bottom to test the maybe-dead ones, if they're the same (I dunno, don't have that case). That'll tell you if the bulbs are the problem or something else.
