Just getting my 67 back from the paint shop and would like to put led lights on the tail and park lamp. I see a kit online that goes in the place of the bulb in the tail lamp on a standard camaro for about 90 bucks. it is a plate with i believe 14 led lamps in it. Has anyone used one and how did it work. I also see led bulbs that replace the standard bulbs. Will these work and do any more wiring revisions have to be made? Is there much difference in brightness? What about replacing the sealed beam headlamps with the replaceable halogen bulbs? Too many questions? Thanks!
