The old common standard for a mains stroboscope
was a neon bulb (+resistor).
They are still widely available, simple and inexpensive.
No, they are not very bright and need some shading or otherwise reduced ambient light,

If it works why change it?
Don't modern leds use a still glow after being turned off?
