I agree

lift the turn sig stalk slightly to see if it comes on.

I don't know how many times I got pulled over for the left rear tail/brake light out.

I would always lift the stalk to make it work.

chased it for yrs till an old mopar guy said "just" change your TS switch.

and "BOY" on that 68 if you adjust the reverse light switch on lower column they will go off when in drive.
