I got rid of the LED. It wasn't bright enough to be a dependable safety warning.
I did test the 1206 resistors. They failed at just below 3KV.

Actually, I'm using some resistors that we have in stock, not specifically high-voltage parts. They won't actually fail at 500 volts (they do fail around 3000) and a resistor failure wouldn't be a safety hazard.

What about a year or three down the road?
Life is risky.

Sure, and I don't need to tempt fate. Smoke three years down the road is much worse than smoke in the lab.
The measured safety factor is over 6:1.
Actually, that Yaego 1206 resistor that's in stock is rated for 500 volts.
