I know this has been discussed, however I want to ask a few questions. First off my headlights are stock for my 1971 cj5. I have added relays for the low and high beams. Do I just buy the 7" round headlights that have the H4 bulbs and plug them into the 3 prone plug? Do I need to make any cuts in the headlight buckets? Is the upgrade noticeable?
