I've got the same units but they're on a telescopic pole. Nice little bits of kit and they last forever. But as with LED's when the power goes they go, no warning ie., they don't go dim first. So pack spare batteries and remember to keep checking the spare batteries as the lights don't drain much so chances are your spares may be knackered by the time your lights go out!
I'm wondering if you are confusing these with the white 360 stern light that has to be high enough to be visible with the boat at any angle.
The lights in the pictures are the red/greens that go on the bow, which need to be visible from the front & sides, but not from behind.
