I take responsibility for myself but I'm not buying an unproven Yellow Star jacket for anyone and I'm definitely not taking responsibility for random other cyclists - especially not
@Justinslow who disobeys highway code rule 147 with this thread and I believe doesn't use bike lights that comply with the law anyway, based on
past comments.
So in summary: get some legal lights yourself before complaining about others not doing so - and even then, ideally, don't get agitated enough to complain on here
