Utilizing advanced LED technology, the ProBEAM LED turn signals maximize performance with a unique reflector technology and automotive grade LEDs composed into a sealed unit for superior reliability. Building upon our famous Dynamic Ringz, ProBEAM turn signals utilize automotive grade LEDs to produce an even brighter light output with wider viewing angle. The outer ring of 24 white ProBEAM LEDs showcase a smooth white halo that functions as the running light while 12 center amber LEDs function as the turn signal. When a turn signal is activated the White LEDs turn completely off for the entire turn signal cycle providing greater visibility to the amber turn signal.
