for the passenger side... you will probably take off the bolt that retain the windshiel water and pull it behind... its the only solution... its a little bit harder to get to the bulb.. but not at all impossible..! trust me... im not a honda engineer that created that , but i made it serval time for some customer that bougth me hid kit.
if you have any other question. please feel free to ask and i will do my best to give you the good and right answer!
