Our coach has one and when you need it, it's rather handy. Just for giggles I epoxied a mounting bracket on it for the GoPro. We had it up there taping our last trip and it was fun to aim it at different sights along the freeway during daylight without the spotlight "on". The display shows on my smart phone. The battery didn't last long - When you're using the smart phone as a display via Bluetooth it really runs down the battery on the camera.
Fortunately, we got a little bored with it before the battery went completely dead! The spotlight's still pretty nifty, though.
