Re: 98 Accord Sedan Low Beam Bulb - HB4 51 watt or 55 watt? How to Remove/Replace shroud?
Usually all you have to do is press on the clip where the wires enter
the bulb to release the connection and turn I believe counter
clockwise to get the bulb out. I don't think that there is a
difference in the headlight between the 4 cyl and 6 cyl model.
