They certainly look interesting
If these flashers aren't heavy enough to make the springs sag, these could turn into indicator lights. I'll have to find some which just flash red:

While I wardriving yesterday I passed cyclist who had a flashing rear light alternating between a red light & a white light. Is this illegal or just stupid?

White light visible to the rear is always wrong unless a reversing light, properly used. That'll be law, not guidance.
