Purchased a headlight assembly for a 2012 wr450f. I know the plate will bolt right up, but will I need an adapter for bulb? On my 2009 I can't remember if it was a standard 3 prong h4 socket. My bike suspension is being tuned and do not have close access. Will be picking up from MCR friday and would like to get bike together asap. It's getting nice out! New to TT by the way. Thank you!
