Here's a closeup of the slope indicators. They are the 7489C model from R&B Manufacturing who advertise on this site. (816) 587-9814
Welcome to R&B MFG. INC
They were very nice to talk to. I told him I saw his add on
TBN but I did not want the discounted 15 degree model. He gave me a deal since I bought 3 meters (one was a 25 degree model).
The batteries went dead on the camera so I did not get any closeups of the lights. They are the small fog/driving lights from harbor freight.
