The GS Dick Heads are famous for this. When you ride a $25K bike, I guess you have something to prove!
I've been blinded several times by BMW GS guys running TOO BRIGHT LED Aux lights. One guy (on coming) running BIG yellow lights had me target fixating on him ... his lights dazzled me, started heading right at him

... then came out of it ... and flipped the guy off as he passed by.
When I see guys running too bright lights ... I TELL THEM.
The Real issue here IMO, is how much these guys with super bright lights PISS OFF car drivers. And what does that lead to?
More riders getting knocked off by enraged cage drivers. (thanks guys!)
But can you blame the car drivers?
I would urge riders to ease up on the bright LED lights ... and really look after the aiming of those lights. If you're riding across the Baja Desert ... at night ... like I've done, that's fine, but in day to day City riding, it's just an Ego trip and really endangers other riders ... and promotes even more cases of ROAD RAGE .... where bikers always lose.
