Well, if not your sex appeal, your visibility at least.
Believe it or not, I got whistled at by girls in Troon last night more than
30 years my junior. They may well have been drunk but then again, they might
not have been. ;-)

Runs off 2 AA cells and is surprisingly bright. I bought mine in a DIY
store (B&Q) for
£7.99 although I'm sure you can buy it cheaper on-line somewhere. (Try
Googling for "glow wire" or "electroluminescent wire"😉. It can be set to
blink or provide a steady light.
Might not be any more effective than a reflective bib but it's just *so*
cool.
