Okay, exchanged them for the 60XT's but now I have an odd question......why are they upside down???? LOL

The post for mounting them seems like it was designed to hang them down from above. The Gobi rack mounts them from the bottom - hence the damn light is upside down. No big deal, just wondering what was up with that??
On a better note, thanks for the advice, Phil. They DO fill up the spaces at the rear of the Gobi very nicely. A perfect fit if the damn bulbs weren't upside down.
