Stedi EVO Light Bar 22 InchDESCRIPTION GOOD GENES RUN IN THE FAMILY. We celebrate the birth of the STEDI EVO Light Bar, one year after the arrival of the TYPE X EVO LED Driving Light. Injected with a decade of ideas, refinements, and improvements, we have yet again set our sights beyond typical shapes by creating the STEDI EVO family, redefining auxiliary driving lights across the whole category. They say good genes run in the family and the EVO Light Bar is no exception.
