Need some L.E.D bulb schooling

You certainly won't damage anything by installing them. They take much less power to run, and cannot damage your car in any way. I have put LEDs in the turn signals front & rear, backup lights, and brake lights of my '69 Dart. And for some reason did not need to change the flasher unit either. I think the reason is because many of the old flashers in our cars have already been replaced by the newer solid-state flashers. I got my bulbs from superbrightleds.com
