This is my first Kaw, I know nothing, trying to learn and not make mistakes when ordering parts. please be patience with my questions. I have read all the previous post about pulling the bulb and as odd as it may sound the bike tool kit didn't even come with a screwdriver.
Well your 2013 ZX6R has 2 running lights and then a Low beam and high beam. If you want both High and Low beams to be HID then you would need two separate kits. Most guys only run the HID on the low side because the time it takes for the bulb to warm up, will delay the high beam some. Both bulbs are H7 model bulbs. Purchase 1 H7 kit for the lowbeam only, and purchase 2 H7 kits if you want low beam and high beam to be HID.
This bulb will just replace whichever bulb you choose to replace, whether it is high beam or low beam. If the high beam bulb is replaced, when the high beam is activated it will come on with the HID light. The same thing goes for the low beam.
