ive got a 87 honda shadow vt700c. I am looking to upgrade the headlight from the factor light to something that is brighter due to the fact that i ride at night a lot. The problem is that im not sure if i can just get a brighter bulb or if i will have to replace the whole light. Ive looked into just changing the bulb with a oem bulb but the part number has been replacved with a diffrent part number. The replacement bulb from what i have read is not fitting like the original bulb. I was just hoping that someone could help figure out weather it would be better to change just the bulb or the whole headlight unit and if you have any suggestions on which product i should go with.
