I have a problem with the turn signals and brake lights on my 66 coupe. My tailights work fine as do my headlights. When I hit the brakes nothing happens with the lights. Likewise when I use the turn indicator nothing happens. My car is a GT clone and has the dual exhaust coming out of the ground effect addition. Should these lights indicate turns or what? I have a Chiltons manual and find it a bit confusing and am waiting on my shop manual to arrive. Anybody have any idea why my brake lights and turn signals are not working?
