Anyone notice if you start out in 1st gear and lug the engine by accident the LEDs blink in and off. I find that interesting. BRZ only?

It's because they don't properly drive the LED's and only use resistors.

The "boomerang" LEDs have a proper LED driver, so they don't get affected like that.


Even the boomerangs don't have drivers, but they have a bit more circuitry that doesn't allow them to drop out as easy as the DRL's.


It's a shame how normal it is for the OEM's to skimp on driving the LED's properly...
