The low beams have nothing to do with this, so you go with any LED upgrade and it’s not affected.
However, since the high beam lights are used for both high beam and DRL lighting, and they are sent two different power signals, a LED bulb without the proper driver will not operate correctly when it is sent the pulsing power signal (DRL active).

Thanks, for the break down of that I wasnt thinking about DRL being the day time running lights I was thinking it was the CANBUS that was needed to run these LED lights. What Katana lights did you get.
