Default Rear tail light issue 1976

I just replaced my BU lights w/solid reds like the outer .Bought new sockets and tapped into the existing wires on the outer lights.All TL come on.brake lights work,pass turn signal works but drivers side turn signals flash alternatly,not together.Checked the wiring all good.What is up? Anyone have this same issue and what fixed it? Thanks

If they are flashing alternately, they are back feeding.
Bottom line. You have a bad ground on that side.

Well got the flashing issue resolved,didnt have bulb in all the way but have a new issue. All rear tail lights work as they should but brake/turn signal on new light on drivers side doesnt get brighter,stays the same. I switched out bulb even swapped sockets and still have this issue.Stumped.What could it be?Thanks
