show us a peer reviewed article that shows that bright bicycle lights cause car crashes.
i have looked for such peer reviewed articles and found nothing.
We're talking about light here, not the piece of metal it's mounted on. Very bright bicycle lights may well be so new and so infrequent that they have not been the subject of academic study. Have you found any peer reviewed studies on the subject -- if not, then peer reviewed studies are irrelevant to your claim.
There are laws and findings and reports and anecdotal evidence on the subject of bright vehicular lights. And a light that is too bright is probably just too bright whether what's behind the light is a driver or a cyclist.
