It’s funny how some niches get EXTREMELY well-solved with good engineering (e.g. computer cooling) and yet never marketed for use cases beyond the original very narrow case, despite being very capable & cross functional.

I often reverse a large trailer in unfamiliar places at night. I was looking for 2x “red torch” to be markers. Every torch I found was either hideously expensive or not rechargable / only charges with USB-A. Until brainwave: rear bicycle lights are cheap as chips & USBC!

Two red “rear” lights for bicycles. They are strapped around tiny plastic boxes so that they can stand on their own when placed on the ground. An extra detail as a treat to YOU as a reward for reading the alt text - the tiny plastic boxes are actually oversize lego blocks which were originally salt and pepper shakers
