In the late 80's early 90s in NL, I got a ring of reflective plastic tubing with a wire in it.
it laced in amongst the spokes , above the rim.
so while the reflective bands in sidewalls dimmed from brake use side effects this did not ..
IDK what happened to Them after Continental and Schwalbe began producing tires with the embedded ring
the market may have disappeared ..
Any color added is over the silver base and is a Filter , it only lets Red light wavelengths thru. and so by that is Dimmer .
Maybe a red tire with a silver reflective band exists IDK.
