Did they work before?Did you check the tail frt park lights on the first notch of the headlight switch?If I was close Id stop and give you a hand.Electrical for most of the early cars isnt black magic.But with a factory manual its pretty easy to figure out.First thing is you have to make sure the fuse for the park- tail lights is good and suppling power in and out.Not hard just get a cheap test light.Rocky
