Looking at my 78 Wiring schematic cd:
Red/bk stripe comes out of the brake switch and goes to turn signal assembly (1 wire). It comes out of the turn signal assembly as Yellow/bk stripe to the left side rear brake (1 wire), & Right side rear brake is powered by green (1 wire). Parking lights, marker lights, & tag plate lights at the rear are powered by a brown wire direct from the headlight switch.
I had a similar problem a couple years ago, very dim brake light on the left. Came down to changing the socket to fix. It was losing power inside at the brass tab.
