Interesting. I followed a guy out Queens Blvd and his Blinkie was blinding me. I had to not follow behind him and avoid looking the blinkie. When I caught up, I asked what Blinkie it was and ordered one for myself as soon as I got home.
If someone gives me unsolicited advice that my blinkie is too bright, I'll give some unsolicited advice of my own: Back off my ass and don't look at the light.
This is basic driving 101 here. Don't tailgate, and look away from oncoming lights.
