Driving a Bar-graph LED Block With a Range of HV
Large value resistors making a voltage divider to shift the level (or, you know, divide it), and the hoary old LM3914 dot bar display driver which is still in production (perhaps unlike its old friends LM3915 and LM3916, at a quick look of what's in stock - well, digi-key claims to have all 3, so maybe that's better now) - made for the job.

Adjust values to suit your unspecified high voltage. On a quick scan of the datasheet to refresh my memory, you should scale down to 12V or less. Choose resistors that will take it without flashover/tracking, or use enough in series to handle that problem.
