FlatBoy! At our shop, all shapes matter! And we think it's a shame that there aren't enough squared-off shrouds for retrofitters working on rectangular reflectors (say that 3x fast!). The all new FlatBoy shroud rocks a 3-sided Type II white/amber switchback light pipe on the front that's extremely bright thanks to its BMW-like optics. Not only that, but they also incorporate a "dim" white trigger for perfect DRL functionality.
