These dang reflectors are such a problem. Why did BMW even put them on? They have no light behind them like turn signals. Anyway, I posted my opinion regarding these things. I went with the carbon fiber look. They definitely stick out but it matches well with my other CF mods over mineral white. My thread is here somewhere but here's a pic. They are from AutoTecknic for $108 then shipping. Perfect fit, flush all the way. Pricey but the painted ones are not that much less, $70s??
