I'm assuming this is for the FRS since the BRZ uses the LEDs for DRL?
There are plenty of studies that show DRL implementation dropping multiple car accidents (2 people involved, not indicating 3+) by 10-30%!

I know it might not look "cool" but the facts surrounding the use of them are hard to argue against.
