I just went out to the garage and took a few photos. The first is looking down at the top of the bar, taken through a grill slot. Second is a close up of the end of the light bar, and the third is from under the Expy looking up at where the bar is mounted.
I would have preferred to go higher, but it is really quite effective where it is.
The photos didn't import with correct orientation. You may need to use your imagination. On a fairly old Macbook, if I select open attachment in new tab, the images show correctly. YMMV
