I just wired my rear lights and turn signals, tail lights, stop lights all work. Since turn signals share the same wire with stop lights to the rear. When stop lights are on the turn signal is not. So unlike a modern car when stopped and turning only brake light is on until I take foot off brake. Is this accurate operation for 1955 chevy truck 2nd series? Also did that truck come with flashers / hazards? I can’t locate anything in the wiring diagram or manuals. Thank you in advance for any guidance. Mark
