I just bought a K&S control switch (12-0040) to D/S my '03 WR450. After searching, it seems that there is one power input to the switch for the headlights and tail light/brake, and another for turn signals. I would rather not convert the bike to all DC, instead, I want to run the headlights and tail light on AC and everything else on DC. Does anyone see any problems running both AC and DC in this switch? Has anyone had any problems running the 55w AC headlight through the switch which is supposed to be good for only 23w? Will it be OK to keep the tail/brake light on AC? Will there be any problems between the AC and DC grounds? Thanks in advance.
