I reckon a night EOL going from the very bright lights of Vegas into a dark parking lot or park would be pretty horrible, with or without a landing lamp.
Can't post it, but I have a video of a police Schweizer 333 that suffered engine failure and had to autorotate at night in a built-up urban area. Crew survived but hit a wire just shy of making a car park. They did a great job, but even then...
