Hi, you need to check wiring circuit to lamp assembly. Left side, dark green wire with red tracer, carry voltage for turn and brake, step on the brake, use a testlite, see if wire is hot. Also, black wire is ground, check that as well. The lower brake and turn use the same bulb filament, just not at the same time. Voltage comes from multifunction swich.
