Like I said, that's approximate, and if you'd been specifically informed of it via a NOTAM the responsibility is yours as a pilot to avoid it. If the NOTAM said it was 770ft high you'd be very irresponsible to buzz it at 800ft.
If the warning light hasn't been working they could have filed a NOTAM for that. For all I know that may have been what the NOTAM said, I've not seen it. But a pilot should not be reliant on warning lights alone, it is also their responsibility to be within the VFR mimima when flying visually as I said.

@pipwish - thanks, it's not hard, sadly...
