I'll have these in kmph in carbon now mate. Also, can you tell me how many lights to replace all in the dash?

EDIT: ok, big thanks to the tech wiki, the dash takes 9 bulbs in total, seven inside gauges, two on oter edge, which would be the turn signals. So my question is (bear with me as I dont have my car atm so cant check for myself) how many of these do i replace with blue leds, and how many, if any, do i need to keep white because of coloured plastic filters ie high beam, oil etc??
