Another way that's a bit lower tech is (if you have black bits on the bike or helmet) black reflective tape. Stealth in the daytime, lights up when illuminated. But of course that's nothing like this.
Not my kink , looks very tacky. Actually reminds me of a mates bike, he has one of those 900 Kwakka cruisers , all customized big wheels, fancy paint job , bars etc etc , trying hard to look like a harley. Noticed a switch on the side cover he hits it and the bike lights up underneath with LED's , straight up i started call it " A low flying Japanese UFO" he doesnt like that hahah
What is it with skulls and monster heads and dragons on motorcycles? Deep breath, let it go....
As for lighting the bike up like a Christmas tree - do they think everyone who rides a bike has the mental age of a 5 yo????
Anyway, interesting idea this paint. Imagine hitting your brakes and the whole rear fender lights up. And you could put indicators wherever you wanted them - invisible yet visible. Not sure I'd bother but some possibilities there for sure.
